Blood on the Dance Floor: HIStory in the Mix is a remix album by Michael Jackson released in 1997. The tracks on the album included eight remixes of songs from Jackson's previous album HIStory - Past, Present and Future, Book I, and five original songs ("Blood on the Dance Floor", "Morphine", "Superfly Sister", "Ghosts" and "Is It Scary"). Jackson dedicated the album to Sir Elton John to thank him for the support Elton had given him during Jackson's struggle with addiction to prescription painkillers.
On April 2, 1997, the debut single from the album, "Blood on the Dance Floor", was released in Europe. The single peaked at #1 on the UK Singles Chart. The U.S. release of the single was less popular, peaking at #42 on the Billboard Hot 100 chart and #19 on the R&B chart.
The second single from the album was "HIStory/Ghosts", which included the official Tony Moran remix of "HIStory" as a double A-side track. On May 8, 1997, Jackson, in collaboration with director Stephen King, made a 40-minute short film titled Ghosts. The film premiered at the 50th Annual Cannes Film Festival. The short film was positively received by critics who attended the premiere screening. The short film helped propel the single to #5 in the UK.
"Is It Scary" was planned as a third single but was never officially released (as of 2006 only a few promo singles remain). The song was intended to be the theme song for Addams Family Values, but this didn't happen in the end. It was also featured in the Ghosts short film.
It has been rumoured that the track "Superfly Sister" is written about the abusive relationship between his sister La Toya Jackson and Jack Gordon.
On May 14, 1997, the album was released worldwide, and was certified platinum by the RIAA in October 2000. Nielsen Soundscan scanned 276,860 copies of the album through to April 2007. Worldwide, the album has sold an estimated 6 million copies making it the best selling remix album of all time.
