T.I. and Christina Aguilera reflect on the hardships of being a superstar on “Castle Walls,” the new single from Tip’s seventh album No Mercy (Dec. 7). Produced by Alex Da Kid and co-written with his artist Skylar Grey, the somber tune shows the King of the South at his rawest. “The dangers don’t equate to all the time it take away from ya kids,” admits the incarcerated rapper during his introspective verses.

“It’s hip-hop, it’s electro, but I think it’s gonna lend itself to a broad audience,” Alex Da Kid previously told Rap-Up TV. “It has some kind of substance to it in the lyrics. It should work on radio and in the club, hopefully.”
