There was already a thread for last.fm users. I really like it, but I prefer to add people only if they're friends or have a similar taste
last.fm/user/drericfautstein thats me. i use it mostly for finding new material though. Ive only been a user for a few months but my loved tracks are good. i am mostly into classical/brazilian jazz and electronic / idm/ downtempo / ambient / whomp stuff. gimme a hollar! yea : )
http://www.last.fm/user/simdaddy I love the website. I don't see why more of my friends aren't on there. I've been using it to archive my listens for years, but I'm only just now beginning to learn how to use it to find new music. What an exciting time we live in, for all of this to be possible!
