"Fantasy" is a song by American singer and songwriter Mariah Carey. It was released on September 12, 1995 by Columbia Records as the lead single for her fifth studio album, Daydream (1995). The song was written by Carey and Dave Hall, both serving as primary producers alongside Sean Combs. The song heavily samples Tom Tom Club's 1981 song "Genius of Love," and incorporates various other beats and grooves arranged by the former. The song's lyrics describe a woman who is in love with a man, and how every time she sees him she starts fantasizing about an impossible relationship with him. The remix for the song features rap verses from Ol' Dirty Bastard, something Carey arranged to assist in her transition into the hip-hop market.
