Vibrator is an unreleased song recorded in Summer 1983 at Prince's Kiowa Trail Home Studio in Chanhassen, Minnesota. It was intended for Vanity 6's planned second album. When Vanity left the group and decided not to participate in the Purple Rain movie, Prince instead began the group Apollonia 6. The song is not known to have been considered for the Apollonia 6 album.
The track is an ode to the battery-operated sex toy. The narrator (Vanity) sings about her vibrator, before the song transforms when the batteries run out in her toy; she goes to a store where she meets a shocked store clerk, played by Jill Jones, who offers to "take it downstairs" to install the new batteries. The narrator leaves, instead taking it to a different store, and meeting a different clerk (played by Prince in his Jamie Starr voice), who gives her the batteries and rushes her out of the store. She then takes her toy home, and the song ends with her moans and her eventual climax.
Prince gave the song to Eric Leeds in July 1989 (along with You're All I Want, My Summertime Thang, Pickle, U Should Be Mine, Wet Dream Cousin, The Max and XYZ) when considering songs for a new Madhouse album (later called 26, which later evolved into Eric Leeds' solo album Times Squared), presumably to be used as an instrumental; it is not believed that Leeds worked on the track, however.
Vanity's moans from the song have been sampled on a few different tracks. They were sampled at the beginning of Seven (as more of a segue between Six and Seven), before then also being sampled on 24 (Orgasm), originally included as part of 21-24 (The Dopamine Rush Suite) before the section it was a part of was edited out for the track's release as The Dopamine Rush. The moans were included also on Orgasm (released in complete form as Poem).
