T.I. - "Castle Walls" f/ Christina Aguilera


We've all ready heard two new songs from T.I.'s forthcoming No Mercy, formerly called King Uncaged, “Get Back Up” with Chris Brown and “Welcome to The World” with virtuoso Kanye West and his protege Kid Cudi. The newly incarcerated rapper, serving eleven months for parole violations, displays some of his most passionate lyrics alongside Christina Aguilera on the second official single from the LP, “Castle Walls.” Produced by Alex Da Kid, “Castle Walls” houses a riveting electronic friendly beat, one that is elevated during Aguilera's evocative chorus: “Everyone thinks that I have it all/But it's so empty living behind these castle walls.” No Mercy drops December 7th.
