If you saw the music video for "Blood On The Dance Floor" and bought the CD album that included this song, you would have noticed that the CD version was completely different. I call it a scam because you would normally expect to hear the same version on the album. Music companies love to occasionally rip consumers off this way.
That said, this CD single includes several versions of "Blood On The Dance Floor", including the unedited version of the music video version, known as the Refugee Camp Mix. If you liked the music video version, you'll love the Refugee Camp Mix too.
