Whoa!!

Lastfm.com.
This is not spam, if you enjoy music and would like to discover new music, or to socialize with those that have your same taste, download this incredible music program.

Trust me. Think a certain artist is incredible? I bet you could find 30 more that branch off but are relatively very similar to that special artist. All it takes is a few minutes to install and off you go.

Plus, it automatically has a wiki writeup for anything YOU play on your music program, and everything IT plays when you tell it to.
Tell your friends.
