*New Music* Castle Walls - T.I. feat. Christina Aguilera

Probably the best and most introspective record in the last five years from the troubled rapper. It's sad he has to promote the new album inside a cell but as he explains in the music, that's nothing compared to letting his kids down. Most of the other blogs are afraid to post unsanctioned music right now but I needed to let you hear this. King's No Mercy album drops Tuesday, December 7th.

Penned and produced by newcomers, Skylar Grey and Alex Da Kid, who are responsible for a wave of hits including Rihanna & Eminem's "Love The Way You Lie", Diddy & Dirty Money's "I'm Coming Home" and B.o.B & Hayley Williams "Airplanes". The duo's Top 40 sound is pretty remarkable, being described as "Coldplay meets Hip-Hop" and quickly becoming a mainstay on the charts.
