OMFG!! If 2pac stole the concept from this guy, then Eminem's 'cleaning out my closet' was stolen from 2pac. Which means that Kanye West's 'hey mama' was also stolen from both 2pac and Eminem.
WHAT A VICIOUS CYCLE!! THEY'RE THIEVES ALL 7 OF THEM.
pac wrote his own lyrics to the song (like always) and it was sampled by "Sweet Sadie" and another oldschool song i cant recall right now. so i doubt theres any validity to this guy's claims
