41 "Just Fine"
Mary J. Blige
The queen of hip-hop soul goes disco, with an electro-bounce sound rooted in early-1980s club music.
42 "This Ain't a Scene, It's an Arms Race"
Fall Out Boy
FOB get their R&B on? How could it go wrong? Several million ways, actually. Yet the latest installment of Pete Wentz's high-school-USA soap opera achieves greatness.
43 "Us Placers"
Kanye West forms a supergroup with Lupe Fiasco and Pharrell Williams, and samples Thom Yorke for a one-off that can hang with anything on Graduation.
44 "Bleed It Out"
Their simplest song ever, and their greatest — Brad Delson jumps out of the speakers with one monster riff; LP's vocal tag team of Chester Bennington and Mike Shinoda sound more pissed off than ever.
