T.I. and Christina Aguilera reflect on the hardships of being a superstar on “Castle Walls.”
“Castle Walls” is the new single from T.I.’s seventh album No Mercy (Dec. 7).
Producer Alex Da Kid said,
“It’s hip-hop, it’s electro, but I think it’s gonna lend itself to a broad audience. It has some kind of substance to it in the lyrics. It should work on radio and in the club, hopefully.”
