Video: Kanye West: "Heartless" (Live on the "Late Night With Conan O'Brien")

Kanye's relentless promo assault continues with a rendition of "Heartless" last night on Conan. His voice sounds a little rough, no doubt because of all the 808s-related appearances, and it's a little weird to hear a scratchy voice that sounds on the verge of going out run through the Auto-Tune.
