Even with over 1,000 songs in the stash at his disposal, Lil Boosie has pretty much been holed up in the studio working on new material since being released from prison in March.

The Baton Rouge rapper recently debuted the lead single off his upcoming comeback album, 'Touchdown 2 Cause Hell,' but today he lets loose with what sounds like one of his earlier recorded songs, 'Grade A.'

He isn't referring to hard drugs on this B-Real-produced record, though; Bad Azz gives it up for all his bad bitches around the world -- from California all the way to China. You see, Boosie don't discriminate, he regulate every shade of the ass.

Boosie is set to hit Dallas, Texas tonight on his recently-announced U.S. tour, while 'Touchdown 2 Cause Hell' is set to impact on July 15. In the meantime, enjoy the latest serving from Boosie-Boo below.
