I love Last FM  for many reasons. The first being that like geeksugar, it was nominated for a Webby  last week because it's just plain great. The second, being that the site offers an alternative to downloading music  onto your computer and a forum to meet people that love all different types of music.
How does it work? You listen to your music with your computer's music player or your iPod and Last.fm "scrobbles" your playlists, which means every song you listen to with Last.fm becomes part of your music profile. In essence, the site keeps track of what music you listen to, and then produces a large number of features personalized to you.
After that you can create personal music charts automatically, find your "musical soul mates," generate a personal radio station and see what your friends are listening to. The site is free. To learn how to post your favorite sites to the Website of the Day group,
I know that this long list looks scary, but trust me, once you get the hang of it, it'll be a snap the second time around.
