Emotional Pump is an unreleased track recorded on 16 October 1986 at Sunset Sound, Hollywood, CA, USA (five days after Violet Blue, two days before Housequake).
The song was written for Canadian singer-songwriter Joni Mitchell, who had influenced Prince greatly . It was sent to her, but she didn't think it matched her style and she told Prince she couldn't sing it. The track remains unreleased.
