The site could definitely use a better design. I've wireframed something basic that I think is better. I see you've got some improvements on the way and maybe use it to help, although I'm not sure how much leeway Shortform gives you to move stuff around.

Move the leaderboard section down a bit

Put your corpo name in the top left(maybe include a link to your Twitter as well)

Enlarge the song/artist names, social links are good there (although you might get a larger response if you separate Facebook and Twitter and put them right out there)

Make the preview screens larger and underneath the main video with a title/artist visible without mousing over(similar to Vimeo's layout)

The massive slogan and "Learn More" button are really just wasted space, make them smaller to leave more room for the videos
