And just when it looked like the tracks may never see the light of day, Gaga drops the original version of “Bitch, Don’t Kill My Vibe.” The pop superstar can be heard singing the hook on “The LG Mix,” which clocks in under three minutes.

“We feel bad about killing your vibe, so here’s the demo you never got to hear,” said Mother Monster.
