Tales from the Crypt Season 2 Episode 8

A rock promoter has been hearing voices inside his head for the past years. His doctor explains it to be too much time in the music biz. But when he tries to steal money at an Iggy Pop concert he learns the voices to be none other than his conscience. His banker shows up one night trying to blackmail him but he bumps her off. His conscience gets on his back so much that he blurts out her murder and goes to the hot seat to shut his conscience up for good.
