Input: Question: How long were Luis Miguel and Mariah Carey in a relationship? Passage:When the song was first released as a single in 1994, no remixes were commissioned. Carey re-released the song commercially in Japan in 2000, with a new remix known as the So So Def remix. The remix contains new vocals and is played over a harder, more urban beat that contains a sample of Afrika Bambaataa & the Soulsonic Force's "Planet Rock;" it features guest vocals by Jermaine Dupri and Bow Wow. The remix appears on Carey's compilation album Greatest Hits (2001) as a bonus track. A video was created for the So So Def remix, but it does not feature Carey or the hip-hop musicians that perform in the song. Instead, the video is animated and based on a scene in the video from Carey's "Heartbreaker" (1999). It features cartoon cameo appearances by Carey, Jermaine Dupri, Bow Wow, Luis Miguel (Carey's boyfriend at the time), Carey's dog Jack, and Santa Claus. In 2009 and 2010, the song was included in a music video accompanying ESPN's (and their sister station, ABC) Christmas Day coverage of the NBA.
