In the early 1990s, Mariah Carey became one of the first mainstream artists who re-recorded vocals for a dancefloor version, and by 1993 most of her major dance and urban-targeted versions had been re-sung, e.g. "Dreamlover". Some artists would contribute new or additional vocals for the different versions of their songs. These versions were not technically remixes, as entirely new productions of the material were undertaken (the songs were "re-cut", usually from the ground up). Carey worked with producer Puff Daddy to create the official Bad Boy remix of "Fantasy". The Bad Boy remix features background vocals by Puff Daddy and rapping by Ol' Dirty Bastard, the latter being of concern to Columbia who feared the sudden change in style would affect sales negatively. Some of the song's R&B elements were removed for the remix, while the bassline and "Genius of Love" sample were emphasized and the bridge from the original version was used as the chorus. There is a version omitting Ol' Dirty Bastard's verses. The "Bad Boy Fantasy Remix", combines the chorus from the original version and the chorus of the Bad Boy Remix together, removing Ol' Dirty Bastard's vocals from his second verse. Carey re-recorded vocals for club remixes of the song by David Morales, titled "Daydream Interlude (Fantasy Sweet Dub Mix)".
