New song by T.I. leaks!

Although T.I. will be jail for several months,

that doesn't mean he's not gonna release anything until then.

In fact, his upcoming album, No Mercy,

is going to be released December 7th!

While his fans wait paitently,

someone decided to leak a snippet of one of the album's tracks,

entitled "Castle Walls,"

which features Christina Aguilera. In the snippet,

you don't hear much of T.I., but it's okay.

The song sounds okay without him even being there.

Anyway, listen to it and tell me if you think it's album-worthy or not!
