Musicovery!

This site is God.

Musicovery. So many songs, so many great ideas. From the mood player, to the music map, it is amazing! You really must try it. I can honestly say it's better than Last FM, and free, too, so you have nothing to lose by simply trying. Of all the music sites out there, Musicovery is my top dog. I simply cannot endorse this enough. Use it, and be amazed!
