Musicovery is basically what it sounds like - you can "discover" music based on your selections of genres and the mood you want to listen to at the moment.
I was stumbling around and tried the site out and played something by Sweet! I only have one Sweet song and I almost bought the album but was too lazy to do it just then... but the point is Musicovery worked pretty well at the moment.
By the way, I'm trying out StumbleUpon (I'm really behind the times) - so far I like it, and it'll definitely help me in times of extreme boredom while waiting for my camera to get here.
