Roscoe Dash is fed up and he’s not taking it anymore.

The Atlanta rapper took to his Twitter earlier today (September 20) to share his frustration about not being properly credited for his contributions on G.O.O.D. Music’s Cruel Summer album and Wale’s smash single, “Lotus Flower Bomb,” which he claims to have penned for the Maybach Music Group rhyme slinger.

“Everybody go get the G.O.O.D. album and listen to #1 then watch @kanyewest interview … & tell me y I’m not on the credits,” Roscoe began his Twitter rant with. “Can’t do favors for niggas bcuz no matter how humble and generous u r to ppl niggas will take everything u have … Even niggas u look up to. The most talented ppl get the least credit for everything and the crazy part is they put in the MOST work…

“Same shyt with @wale lotus flower bomb I wrote that for him b4 he even signed to Ross & it went #1….but nobody would kno that cuz I’m not in the credits,” he added. “But EVERYTHING must eventually come to the light….& I’m only speaking on this publicly bcuz there are so many ppl who wanna be apart of the industry but dnt Kno half of the shit that goes on.”

Dash’s mixtape, Roscoe Dash 2.0, was released on the Internet last month.—Mark Lelinwalla
