Ultimate is a greatest hits album by American recording artist Prince.

A second release date of May 22 was proposed, but was again canceled and the album's future was unknown for a time.

[10] A two disc promo version of Ultimate was sent to radio stations and record stores in Spring 2006.

The promo features a few songs not on the official release, though it excludes the "Let's Work" remix.

The promo also presents the songs in rough chronological order as opposed to separating out the remixes.
