1. The UX needs some work. It looks late 90s-ish.

2. The name is a little cheesy. I'd really consider changing it.

3. It's not immediately obvious how to play songs. Can you put a play button under each song? Ditto for picking the winner - put a "This is the best song" button under each song.

I do like the music though. :) And it's a cool idea. Have you considered approaching local Battle of the Bands competitions and getting them on the site? Sell it as a all-in-one promotional type of thing.
