Back in January, 50 Cent teased this new song, "Crazy", with PnB Rock and fans anxiously awaited the full version.

Well, now, after about three months of a wait, 50 finally comes through with the official version with Philly's own PnB Rock on the chorus. 

This one bangs as it tells a tale and has a sound that's not heard too often in the mainstream realm. The record even gets somewhat personal as 50 raps about some dark moments in his lifetime.

Peep the brand new cut below, and be on the look-out for details of the album, "Street King Immortal" this year!
