i think Ross put the last nail in the coffin for him, he hasn't been the same after that
50s musical fall off got nothing to do with Ross or any other nikka he beefed with. His fall off is because of all these other things he started pursuing, acting, video games, other business related shyt. It's the same reason Kanyes music has started to suffer as he continues pursuing fashion. shyt happens.
Ross has no relevant 50 cent diss records that made an impact on 50s career. If you look back at the beef, they was getting in Ross ass, then everything just stopped. Props to Ross for continuing to make music his fans would pay and listen to tho.
