T.I. and Christina Aguilera

New Music: T.I. f/ Christina Aguilera – ‘Castle Walls’ [Snippet]

T.I. explains the difficulties of living in the limelight on the somber “Castle Walls,” the latest single from No Mercy (Dec. 7). Produced by Alex Da Kid and co-written by his artist Skylar Grey, the track features a haunting instrumental over which Christina Aguilera sings a touching chorus.

“Everyone thinks that I have it all/ But it’s so empty, living behind these castle walls, these castle walls/ If I should tumble, if I should fall/ Would anyone hear me, screaming behind these castle walls/ There’s no one here at all/ Behind these castle walls.”
