Last.fm

It has been awhile since my last post, again. My summer job just ended, so hopefully I will have a little more time to post (and ideas for topics).
Anyway, This should be a good one for any music lovers looking for something new to listen to.

Last.fm is a music recommendation service. You download their client or use a supported music player. It then keeps track of what you listen to, like and dislike and comes up with a "recommendation radio" station. The client then streams music it thinks you will like to your computer. You can also get a stream based on a tag or set of tags you give the client. In addition, there is a social aspect, but not being very social I haven't tried it out, and the service works fine even if you don't register any friends.
 You can sign up at last.fm (not sure when the .fm top level domain came to be, but it does seem to work) if you want to give it a try. The service is free, though  if you send them money you can get some extra features.
