THE ARCADE FIRE featuring DAVID BOWIE, ''WAKE UP (LIVE)''
What generation gap? Canadian indie rockers the Arcade Fire enlist their favorite experimental rock progenitor (and big fan) to lead a Web-only version of their cataclysmic sing-along. Buy the track on iTunes
THE FUTUREHEADS, ''AREA''
These gifted garage punks show no signs of stopping the rock after jolting eardrums with last year's Clash-y debut. This new spitfire single provides more pulverizing punch. Download it for free here
AYATOLLAH, ''THE DEVIL IS SWEET''

THE CHEMICAL BROTHERS FT. THE MAGIC NUMBERS, ''CLOSE YOUR EYES (LIVE)''
Featuring the hushed harmonies of sibling-stuffed the Magic Numbers, this escalating electro ballad is airy family affair from everybody's favorite big beat boys. This live version is an online exclusive. Buy it at Rhapsody
