The Internet iTunes Registry is a project that allows you to upload your iTunes library file to a central database and get detailed reports on the listening behavior of yourself and the entire community. iTunes provides minimal information on your listening behavior and Last.fm, while much better, is more focused on providing recommendations and community tools.

After completing the free registration, I uploaded my library.xml file. I was pleasantly surprised to see all the available features and tools to help me analyze my behavior including:

• Artist, album and track statistics
• Histogram style listening habits
• Stats about your ratings
• Detailed genre and subgenre stats
• Tons and tons of useful and useless charts
• An interesting set of odd facts about your behavior
• A wallpaper generator

The one thing that bothers me most about the project deals with genre mapping. iTunes lets you assign custom genres, which can cause problems when calculating community statistics. To simplify the charts, IIR asks you to map all of your genres to their predetermined set. Unfortunately, this set only contains a few basic genres and some strange ones - for instance there is a rockabilly genre but no R&B. I understand the need for genre mapping, but IIR should use the default list that is used in iTunes.



There were a few performance problems here and there, the UI could really use some polish and I could not get some of the tools to work properly. However, It is definitely worth checking out if you’re like me and always wanted to know how many hours you have actually used iTunes since installing it and what your least recently played song was.
