Megamix

A megamix is a remix containing multiple songs in rapid succession. It often features various artists, unlike a medley, which features one artist each. There may be only one verse or even just a brief chorus of each song used, sometimes in addition to samples of the same or other songs. It is common to use different samples to maintain and sometimes even ridicule the original. To unify the songs together smoothly, a single backing beat may be added as background throughout the megamix, although this is not a must. This backing beat is kept basic so as to simplify mixing and to not compete with the music. These mixes are usually several minutes long at minimum, going up to a half-hour or an hour, or even more sometimes.

Ultimix is known for "flashback medleys" producing at least one or two every year based on popular songs of the year. Each is about 15 minutes long, usually with at least that many songs if not more.

"Album megamixes" feature all tracks from a particular album edited and compiled into one continuous medley. The "artist megamix" is also popular, including songs spanning a musician's career, with prolific artists such as Michael Jackson having more than one, usually from different remixers. Duran Duran created a megamix single from their own hits for the 1990 greatest-hits album Decade: Greatest Hits. Subsequently, artists such as Madonna, Britney Spears, and Janet Jackson have also released megamixes as singles in order to promote their greatest hits albums or in the latter's case, studio album. Many megamixes are bootlegs.
