Current version is 220.127.116.11 released on 2013-03-15
Other Editions: iTunes for Windows | Winamp | Windows Media Player
The Now Playing plugin allows you to easily publishing what you are listening to! The end result is something that could look like this on your web site!
iTunes allow you to create plugins that can do various tasks for you. The Now Playing plugin monitors the song you are listening to and publishes the data in various ways:
- Creates a XML file with information on that song. A file called now_playing.xml is created in your iTunes Plug-ins directory.
- The plugin also offers you the ability to upload that file to a server of your choosing after it is updated.
- Create a ping with the song information.
- Post information on Twitter.
- Post information on Facebook.
The idea is that you publish the XML up to your web server and then through some scripting magic, you can display your currently playing song or your recently played tracks. To make your web site more interactive, the plugin also retrieves the following information for you to use:
- URL of the album image cover art from Amazon.com (if found).
- Link to the Amazon.com product page for the CD (if found).
- Link to the Apple iTunes Music Store product page with the song highlighted within iTunes (if found).
- Run the installer.
- Start iTunes.
- The first time you start iTunes with the plugin installed, the configuration screen will come up. If you don't see it or you miss it, you can reopen the configuration screen at any time by selecting Now Playing as the Visualizer. In the latest version of iTunes, you can do this on the View, then Visualizer menu. Then return to that menu and choose the Options item.
About: Get version information.
Options: Configure a few basic options for the plugin.
- Publish Stop: If you want the plugin to publish a message when you stop playing music.
- Artwork: If you want the artwork to be exported locally, check this option. The files will be placed in the same directory as the XML file configured on the XML tab. This option is independent of the artwork setting on the upload tab. Only check this if you want the image files to be saved on your computer.
- Artwork Width: Specify the the width of any exported images (both local and uploaded) if the cover art image is wider than the given value. Setting the value to 0 will cause no resizing to occur. The height is calculated based on the width-height ratio of the original image.
- Skip Shorter Than: If a track is shorter than this number of seconds, the track will be skipped from all output interfaces (XML, Twitter, Facebook, etc.). This is helpful if you have short sound effects in your playlist that you do not want to publish. If set to 0, the setting is effectively disabled and all tracks will be published.
- Skip Kinds: If a track matches this list of kinds, the track will be skipped from all output interfaces (XML, Twitter, Facebook, etc.). This is helpful if you don't want to publish video, for example. This is a comma separated list of values. The value for each kind should be taken from the XML's kind tag.
- Logging: If you are not getting the results you expect from the plugin, you may want to enable logging. The log will be generated in the Mac OS X Console.app. If you contact me about an issue, I will be more likely to solve your issue if you send the log file with the event captured at the debug log level.
XML: Configure some options for the XML file that will be generated.
- Output File: Specify the location of the file that is created when the song changes. This file will be uploaded to your FTP server if configured to do so.
- Wrap XML tag values with CDATA: Some song properties have odd characters inside of them and you may need to safely encode the XML depending on your parser.
- Playlist Length: Enter the total number of songs that you want to publish in the XML file.
- Encoding: Select which type of encoding your want for the XML. UTF-8 is the recommended choice.
Upload: Enter your server information to configure FTP or SFTP. Be sure that you have permission on your server to upload the file.
- Protocol: Choose from None, FTP, and SFTP.
- Hostname: Your FTP/SFTP server name or IP address.
- Username: Your FTP/SFTP login.
- Password: Your FTP/SFTP password.
- Artwork: The plugin will export the album artwork for the current track and upload it along with the XML if checked. The image will be resized to be a maximum width of that specified on the Options tab. This option is independent of the artwork export setting on the Options tab.
- Reset Export Cache: The plugin keeps track of the last time it uploaded a piece of album artwork. It will then skip uploading that same piece of artwork again. To clear the cache, you can press this button. You would do this if you are changing web servers or just want to refresh your artwork.
Ping: The plugin can send an HTTP POST request when the song changes. The request is sent after the upload of the XML file, if configured. Each of the XML tag names for the track are posted as fields.
- URL: Enter a URL that will receive the POST request.
- Extra Info: Enter a value that will be sent as a HTTP header called X-NowPlaying. You can use this to set a secret value that your script looks for to prevent unauthorized use.
Twitter: The plugin can post a tweet with what you are listening to.
- Enabled: Turn the feature on or off.
- Rate Limit: Enter the minimum number of minutes between tweets. This is used to comply with Twitter's rate limiting. Also helps so you don't annoy the crap out of your followers with a tweet for every track you play.
- Message: Enter the text that you want to post for each new song that plays. You can use a combination of the tags listed below the field for the song data. The text will be substituted and should be less than 140 characters (Twitter limit).
- Setup: You need to complete the three phase setup to add and authorize the plugin to work with Twitter. 1) Press Authorize to launch a web browser and give Now Playing access. 2) You will get a PIN from Twitter that you enter in the field. 3) Verify the PIN by pressing Verify. 4) You should see your Twitter name appear there with an option to reset if you want to start over or remove the association.
Facebook: The plugin can update your Facebook feed with what you are listening to.
- Enabled: Turn the feature on or off.
- Rate Limit: Enter the minimum number of minutes between posts. This is used to comply with Facebook's rate limiting. Also helps so you don't annoy the crap out of your friends with a post for every track you play.
- Caption: Enter the text that you want to post for each new song that plays. You can use a combination of the tags listed below the field for the song data.
- Description: Enter the text that you want for the description of the news feed item for each new song that plays. You can use a combination of the tags listed below the field for the song data.
- Setup: You need to complete the two phase setup to add and authorize the plugin to work with Facebook. Press each of the buttons in sequence and follow the instructions. You should see your Facebook name appear there with an option to reset if you want to start over or remove the association when you have completed the steps.
Amazon: The plugin will query Amazon.com for additional information about your song, such as a link and the album image cover.
- Enabled: Turn the lookup on or off.
- Locale: Choose "us" for Amazon in the US, "ca" for Amazon in Canada, "uk" for Amazon in the United Kingdom, "de" for Amazon in Germany, "fr" for Amazon in France, or "jp" for Amazon in Japan.
- Associate ID: Amazon allows you to collect referral fees on items sold when users click-through from your site. Enter your associate ID here.
- ASIN Hint: Check this box if you want the plug-in to assume the value of the track’s grouping field is an Amazon ASIN. Since Amazon's search is quirky for some albums, you can use this feature to specify the exact album you want to match.
Apple: The plugin will query Apple's iTunes Music Store for additional information about your song, such as a link.
- Enabled: Turn the lookup on or off.
- Affiliate ID: Want to receive a commission when users click-through and buy songs from your site at the iTunes Music Store? Join the Apple iTunes Affiliate program. Once you join, find out what your ID is by using the LinkShare link generator for any song and extract the ID parameter from the URL generated.
License: If and when you purchase a license, you will enter your registration information on the license tab. Enter the e-mail address you used for the PayPal transaction and the license key I sent you after the purchase.
The XML has the following format for a single song playlist. If you configure the playlist for more than 1 entry, there will be multiple song tags.
<?xml version="1.0" encoding="UTF-8"?>
<now_playing playing="1" timestamp="2007-09-08T23:12:46Z">
<kind>MPEG audio file</kind>
<comments>I like it.</comments>
- Q: I lost my registration key. Can you resend it?
A: You can retrieve it yourself here.
- Q: Twitter isn't authorizing. What do I do?
A: Read this.
- Q: FTP isn't working. How can I turn on passive mode?
A: Passive FTP is configured through the Mac's System Preferences applet. Go there, then pick the Network icon. Choose the connection you are using and then go to the Proxies tab. Near the bottom you will see a checkbox that indicates whether you want passive FTP or not.
- Q: How do I uninstall the plugin?
A: Browse to /Library/iTunes/iTunes Plug-ins and delete Now Playing.bundle. A lot of people mistakenly look in their own personal user Library folder. It is not in there! It is in the system Library folder which can be found at the root of your hard drive.
- Q: How can I get a debug log?
A: Go to the plugin's configuration screen and select the Options tab. For Logging, select Debug. Reproduce your issue now. The logs will be written to the system logs and can be viewed with the Mac OS X application Console. This is in your Applications->Utilities folder. Screenshot.
- Q: How can I get back to the configuration screen?
A: To configure any plugin, you must select it as the Visualizer. In the latest version of iTunes, you can do this on the View, then Visualizer menu. Then return to that menu and choose the Options item.
- Q: If I turn the visualizer off, will the plugin still run?
- Q: Why does part of my album cover get cut off in the Visualizer?
A: This happens because you have "Small" mode selected. Change to "Large" on the Visualizer menu.
- Q: Why aren't my Amazon or Apple links populated in the XML?
A: It is because the Amazon or Apple search engine cannot find the album. These engines can be picky at times.
- Q: Can you show me how to parse the XML file on my server?
A: Sure. This sample will work for a single song or multiple songs.
$file = "now_playing.xml";
$xml_parser = xml_parser_create();
if ( is_file( $file ) )
$fp = fopen( $file, "r" );
$data = fread( $fp, filesize( $file ) );
fclose( $fp );
xml_parse_into_struct( $xml_parser, $data, $vals, $index );
xml_parser_free( $xml_parser );
if ( $debug )
echo "Index array\n";
echo "\nVals array\n";
if ( $vals[ $index["NOW_PLAYING"] ]["attributes"]["PLAYING"] == 1 )
foreach ( $index["TITLE"] as $i => $j )
$title = $vals[ $index["TITLE"][$i] ]["value"];
if ( strlen( $title ) > 0 )
$artist = $vals[ $index["ARTIST"][$i] ]["value"];
$album = $vals[ $index["ALBUM"][$i] ]["value"];
$genre = $vals[ $index["GENRE"][$i] ]["value"];
$kind = $vals[ $index["KIND"][$i] ]["value"];
$track = $vals[ $index["TRACK"][$i] ]["value"];
$numtracks = $vals[ $index["NUMTRACKS"][$i] ]["value"];
$year = $vals[$index["YEAR"][$i] ]["value"];
$comments = $vals[ $index["COMMENTS"][$i] ]["value"];
$time = $vals[ $index["TIME"][$i] ]["value"];
$bitrate = $vals[ $index["BITRATE"][$i] ]["value"];
$urlamazon = $vals[ $index["URLAMAZON"][$i] ]["value"];
$imagesmallurl = $vals[ $index["IMAGESMALL"][$i] ]["value"];
$imageurl = $vals[ $index["IMAGE"][$i] ]["value"];
$imagelargeurl = $vals[ $index["IMAGELARGE"][$i] ]["value"];
$filename = $vals[ $index["FILE"][$i] ]["value"];
$artworkID = $vals[ $index["ARTWORKID"][$i] ]["value"];
echo "Now Playing is " . $title . " by " . $artist;
echo "Now Playing is stopped.";
- Q: I don't understand all of this PHP stuff but I still want to do all these cool things. Can you help?
A: Ok, I have zipped up the actual code I use on my own web site. You can download it and use it for your site or as a starter. Please don't mail me to customize it for you. I don't have time. So to use this: 1) Take the zip file and extract and place the files on your PHP-enabled web server. 2) Put the images into /images on your server. 3) Insert the following code in the web page that you want to display the music.
I have done my fair share of free plugins lately. This one took a little more work so I decided to release it as shareware. So download the plugin and test it out. Make sure it does what you want. Once you are happy, order the licensed version for $5. You will receive a registration key via e-mail once I receive your purchase confirmation from PayPal. Oh yeah -- be cool and keep your registration to yourself.
Also, if you would, you can put the Now Playing badge on your web site with a link back to this page. The more people that donate, the more I will be asked to develop new and interesting features that you will be able to take advantage of!
Here is the code for your site:

A chronological list of how we got here.
v18.104.22.168 -- 2013-03-15
- Fixed Facebook integration. Again. Facebook started doing something "smart" when we give them URLs to Amazon albums. It blows away all your custom text and uses text scraped from Amazon. This does not appear to happen with iTunes links. I use iTunes anyway. So I switched to iTunes links and they seem to be showing up more like they are intended, in most cases. In some cases, you continue to get an iTunes text scrape with it. The other choice would be to remove the link all together which might be the next answer.
- Changed the default Facebook message because "actor" no longer works.

v126.96.36.199 -- 2010-04-11
