OOk y does 50 cents song superstar have tha same exact beat as Omarions entourage?!? who stole tha beat from who? who had it first?! idk someone tell me!!

i wanna be a graffiti artist so if anyone knows how to or where i can learn online please tell me 

tupac is a genius and i really dont think he is dead. but anyway.... some ppl are soo fake sayin how much they like him just becuz hes dead they are all over him its sick. even though i wasnt old enough to hear him when he was still alive i still have madd respect and his music is soo deep, he really puts his heart and soul into it
