In October, T.I. hyped up this collaboration with Kendrick Lamar, B.o.B and Kris Stephens, and also said it'll be on Trouble Man: Heavy Is The Head. However, when the final tracklisting arrived, "Memories Back Then" was nowhere to be found. It's safe to say sample clearances played a role in preventing the song from being on the album, so he stopped by Sway In The Morning and let them premiere the song. Listen to the radio rip below.
