Grooveshark made a very nice change to their service: instead of downloading your entire music library each time, it uses HTML5's local storage feature to store it all right on your local machine. This makes Grooveshark load up faster, especially for large libraries (and probably saves them some change on bandwidth too).

Unfortunately, this broke Musicality, which expected to see your library come down the pipe when Grooveshark started. As a result, songs that were in your My Music collection, but not marked as favorites, were no longer being growled.

Happily, this is now fixed. Check for updates!
