last.fm?

Anyone here use it? I like to keep track of what new bands I discover and see what friends are listening to so it's a nice site. 

I searched a thread on it here but it's been dead for two years so figured I'd make a new one.

Yeah, I use Last.FM, but a lot of songs I like aren't in my library.

Here's my account.
