When J. Cole dropped his fourth studio album 4 Your Eyez Only on Thursday (Dec. 8), fans started noticing a strange similarity between the song "Deja Vu" and one of Bryson Tiller's biggest songs, "Exchange." At first it just seemed to be the shared sample (K.P. and Envyi's "Swing My Way"), but now it seems it's more than just the loop.

"Maybe can explain why to y'all why Exchange and Deja Vu sound similar... right ?" asked Boi-1da, who helped produce "Deja Vu" with Vinylz, on Twitter late Thursday night. When Foreign Teck side-stepped the accusation, Boi-1da went at him again, calling him a "thief" and saying, "you're really out here reverse engineering beats. It ain't about money and placements, it's the principle."

While Boi-1da continued drawing attention to the similarities between another Foreign Teck production, Meek Mill's "You Know" from DC4, and "Deja Vu," Vinylz chimed in to explain what happened.

"Me and made that exchange beat first. It was stolen from us by a thief named . Cole song was recorded before exchange," said Vinylz on Twitter. "I sent this thief a video of me making the Deja Vu beat..a week later he post a beat on ig with the same drums. I made him take it down. He said "I'm sorry bro.. I was inspired . I look up to you" few months later he decides to remake the whole beat and give it to Bryson. He even offered me publishing on the song.. why would u offer publishing if you didn't steal it?..."

Teck eventually copped to lifting Vinylz's drums for the Meek record, but he wouldn't budge on the Bryson record: "EXCHANGE however i made myself and sent it to to finish. he got stuck on it and never sent it back."
