He told me where the energy came from initially or whatever and we just chopped it up from there... 50 Cent was my favorite rapper. That's the reason I'm rapping. He showed me you can come from the streets and put out your own mixtapes and come up. No matter what type of shaky thing or whatever, that don't omit what [he's done]... It's so ill.

50 Cent and Fat Joe - 50 Cent isn't one to easily let his beefs go. But even by Fif's own admission, it took too long to move on from his issues with Fat Joe, which started in 2004 after Joe collaborated with 50's nemesis, Ja Rule. The two New York rappers have since put their issues behind them, but they truly started a new chapter with DJ Kay Slay's "Free Again," which featured the two rappers.(Photos from left: REUTERS/Danny Moloshok, John Ricard/BET)

Jay Z and Lil Wayne - Jay Z and Lil Wayne have a lengthy history of on-again, off-again subliminal beefing, starting when Weezy began his rapid ascent with his mid-2000s mixtape takeover.

The two heavyweights ultimately got on a few joints together — songs like "Hello Brooklyn" and "Mr. Carter" — but the subtle jabs have yet to fully subside. (Photos from left: Frank Micelotta/PictureGroup, Mark Davis/PictureGroup)

T.I. and Ludacris - As two of ATL's finest, it's no wonder that T.I. and Ludacris would have some sort of rivalry, but things were taken to a new level when each threw shots at the other on Young Buck's 2004 "Stomp." Some more verbal shots followed, but they stopped in 2008 with "On Top of the World" and "Wish You Would."(Photos from left: Michael N.
