Tyga teams again with "Rack City" producer DJ Mustard for "Hit Em Up," a booming track from Tyga's upcoming Hotel California LP, out April 9th via Young Money/Cash Money/Universal. Tyga goes back-and-forth with 2Pac's ghost on the track, which seemingly stitches together lines from already-released Pac songs. ("I had came across some Pac vocals from a friend," Tyga told MTV last week.) Though it shares a title with 2Pac's 1996 Biggie diss, this song, which features New York's Jadakiss, is not a remake. Stream it, along with 2Pac's "Hit Em Up," below.
