I came across this website(www.thesixtyone.com) today and it's one of the most innovative and well done websites I've seen in a long time. Musicians can upload their music to be listened to and voted for by listeners on the site - sort of a digg.com for music. Musicians also have their own page which they can use to promote their concerts and events. The experience of using the site is really nice, the music keeps playing no matter where you click, so you can feel free to explore, and it's really a lot of fun.
This is a indie music site, so you won't find mainstream music here, but I've already found a lot of music worth listening to. That may mean the voting system is working if you asked me.
