This article lists songs of the A vs B 'mash-up' genre that are commercially available (as opposed to amateur bootlegs and remixes). As a rule, they combine the vocals of the first 'component' song with the instrumental, (plus additional vocals, on occasion) from the second. The commercially available version of the mash-ups that do not use the original performers vocals have been noted. Additionally the songs with an asterisk (*) were released using only the first song's name. Also noted is the inclusion of any other element.
