Back in 2012, Lady Gaga and Kendrick Lamar hyped up a single called “PARTYNAUSEOUS,” which was originally supposed to be included on good kid, m.A.A.d. city, but was scrapped at the last minute. Gaga cited creative differences with Lamar’s camp, but stressed that it was in no way his fault. A few years later during her ARTPOP tour, she repurposed the non-Kendrick-featuring parts of the songs as an interlude. Now, the full version of the track (or at least a solid-sounding demo) has leaked online, featuring two new verses from the rapper. Listen to it below.
