21 by Original Soundtrack

The soundtrack for the card-counting thriller 21 focuses exclusively on catchy club tracks, and subsequently complements perfectly the anxious pace and glammy Vegas subject matter of the film. There are many stars scattered throughout the soundtrack--Rihanna, Peter Bjorn and John, Broadcast, and LCD Soundsystem--but the true stand-outs belong to the lesser lights: Get Shakes, who deliver the electro-disco thumper "Sister Self Doubt" and Soulwax, who remixes the Stones' "You Can't Always Get What You Want" into a swirling mirror ball of breaks and edits.
