lol @ 50 making a career off Beef. Beef records don't sell records. Were Backdown and Piggybank singles? Did those songs make it on the charts? Now where were "In The Club", "21 Questions" "Candyshop" "Just A Lil Bit", "Hate em or Love Em" on the charts? That's what people don't realize, they think the beef records or beef in itself sold albums, it didn't. 50 knew this but somewhere along the way the nigga forgot that and focused too much on beef and not enough on making quality singles that the mainstream would just eat up.
50's career was made off of Hot singles that the mainstream would love, street songs that the real niggas would appreciate, and beef for controversy. Beef played a part but it wasn't a big part and it wasn't what made people buy 50's albums. Youtube was around from 50's inception in the rap game, anyone could just go to youtube and listen to "Backdown" if that's all they wanted, but they wanted the whole product. They wanted that GRODT, they wanted The Massacre...after that, they had what they wanted for the most part.
50 didn't destory Ja Rule's career, people just got tired of Ja Rule. Before 50 blew up Ja's popularity was on the decline. After Pain is Love, Ja drastically declined in sales. His last album during the 50 Beef was an EP filled with nothing but street songs and disses and that still did around 500K, so the notion that 50 destroyed Ja's career is stupid. Then Ja's album after that did around 700K, with New York (street song) as the lead single.
