I have NOT seen enough

This is the coolest use of interactivity I've seen in quite awhile. Kudos Cold War Kids. To promote their new single "I've Seen Enough" they set up a website that gives you control over the song and the band.

You can mix and match four different styles of each band member.

And if you want to single out a specific band member you can mute the others.
The Cold War Kids have definitely set the bar high with this one, I can't wait to see what other bands follow suit.
