Kid Cudi called out Kanye West and Drake during a recent Twitter rant where he mocked rappers who use “30 writers” and call themselves “top 5.”

The former G.O.O.D. Music rapper held nothing back while declaring his “take over.” “Everyone thinks they’re so great. Talking top 5 and be having 30 people write songs for them,” he tweeted. “The days of f**kery are over. The fake ones won't be lasting too much longer. I’m the one they worry about cause they know I don't give a f*** about the corny s*** they do. All my youngins out here reppin, Asap Rocky and the whole ASAP family, Travis Scott, SuperDuper Kyle, Audio Push, Hit Boy, etc, I see y’all. My tweets apply to who they apply. Ye, Drake, whoever. These n***as don't give a f***about me. And they aint f***ing with me.”

It’s unclear what sparked Cudi’s rant. The rapper left West’s G.O.O.D. Music in 2013 and has been an independent artist since. He announced that he would be releasing a brand new 18-track album sometime before the end of this month. He still hasn’t announced a title for it. Cudi signed to Kanye’s label back in 2009 and penned a lot of records with him including “Welcome to Heartbreak” from “808s and Heartbreak” and “Monster” from “MBDTF.”
