Eros is an unreleased track recorded in May or June 1980, at Prince's North Arm Drive Home Studio in Orono, Minnesota, during the recording of the Dirty Mind album. It is not known if the track was intended for this or any other project.
In 1988, Prince asked his engineer Chuck Zwicky to pull out the track from the vault (along with Rearrange, Rain, Extraloveable and Poppa Grooves) and mix it: "When he was on the Lovesexy Tour, I was assigned to go in the vault and provide mixes for songs that had never been mixed." It is not known if there was other plans for that song at that time.
Little is known about the track, but it is believed to be an instrumental.
