We’ve heard more than a handful of songs from the upcoming Gangsta Grillz mixtape with DJ Drama from T-Pain, but he sort of dropped the bomb on the collaborations during his interview with VIBE at SXSW. According to Teddy P, The Iron Way will feature artists like Bun B and Big K.R.I.T.as well as unreleased Aaliyah collaboration. The song came about a few years ago when the folks behind the R&B princess were recording an album and he’s kept it in the stash ever since.
