but it's absolutely incomplete, I listen mostly to lossless audio (flac, shn) and those don't count in last.fm
Now it says Bill Frisell is my overall top artist, which he ain't, I just listened to his one CD I have of him a couple of times, which I tend to do once every 5 years.
I challenge everyone to take a listen to the Raggende Manne though, great Dutch band from the nineties. You won't understand what they're saying, but it's so much fun!
