"Exchange" is a song by American singer Bryson Tiller. It was released on March 8, 2016, as the second single from his debut studio album T R A P S O U L (2015). The song contains a sample of K.P. & Envyi's 1998 song "Swing My Way".
Upon the release of J. Cole's album 4 Your Eyez Only, producers Vinylz and Boi-1da accused producer Foreign Teck (of The Mekanics) of stealing the beat, to Cole's track "Deja Vu" and giving it to Bryson Tiller, explaining why the tracks share similarities. Vinylz said Cole's track was recorded before Tiller's, and that he sent Foreign Teck a video of him making the beat to "Deja Vu", and a week later Teck posted a beat on Instagram with the same drums. Vinylz also alleged that Foreign Teck offered him publishing, a tacit admission that he had reverse engineered the beat. Another producer by the name of GMoney also made claims that he made the beat back in 2013.
