To explain the Michael Penn group I just created on Last.fm - I need to explain Last.fm. Last.fm is an online music community that provides streaming music based on what you listen. You download a piece of software that works with your music player (iTunes, Windows Media, even Linux players) that will then recommend music to you based on your listening habits, compile listening stats, and best of all create your own personal radio station. You can also listen to stations that are based on artists, fans of those artists, genres, etc.
You can also join groups, one of which I created for Michael Penn fans. There currently is a Michael Penn radio station there - but it's only based on 4 members. Join up, it's really addicting and it's radio that doesn't suck.
