Developed in Python in a single afternoon, this OSX app uses the Last.FM API to discover artists you've previously listened to, but who do not currently exist in your iTunes library.

Please be aware, this was an experimental project primarily designed to learn the Python programming language. As such, it is unstable and likely suffers from compatibility issues.

• Last.FM user account
• iTunes 11+

1. Download the application from the app folder, zipped and unzipped versions are available
2. Enter your Last.FM user account login details in the boxes marked Username and Password

• Optional: Use the Min. scrobbles filter to adjust the minimum number of times you must have scrobbled an artist on Last.FM for it to be included. (Default: 10)

3. Click Browse for Library file and select your iTunes Music Library.xml file. (By default this is located in ~/YOURNAME/Music/iTunes/iTunes Music Library.xml)
4. Hit Find missing artists to begin the comparison. Your results will follow shortly.

As this is an old experiment, there are currently no plans to continue developing it.
