Not a big fan of Travis Porter, but I can't say I've listened to much of their music. One thing I have heard often is their instrumental to the track Make It Rain.
Some of my favorite young rappers brought their talents to the track. Wale, B.o.B and Chip Tha Ripper all take the track to the next level. I'm working on getting a version with all three of the artists on one track, but for now, you can enjoy each of them separately.
