Well, if there was a battle between Chris and Rihanna for comeback singles, let me say this now: SHE WON! Russian Roulette is the first single from her new Rated R album coming soon!! Personal in nature, this track has a hauntingly dark background track and soaring vocals from the Barbados beauty. Props to the kid Ne-yo on this one. I am definitely looking forward to this new album!

Lil Mama doesn't wow me with this new joint, but it's not bad. The track is kinda clever, and honestly I'd rather hear her music than her critiques on America's Best Dance Crew - I STILL don't understand why she's on there. Alas, I digress. Shake is a track from her as-yet-untitled next album, so let me know what you think about it. Maybe there's more to Lil' Mama than her lip gloss...
