I'm new to the forums, but I'll try & share what I know Brad Buxer had zero involvement with the original Late 1990/February 1991 of "Blood on the Dance Floor", as that was originally done by Teddy Riley. All of Brad's contributions were done in Late 1996, when Michael told Brad to "finish" the song, which Brad did by simply working over Teddy's original Instrumental. This also includes the drum pattern, which was of course added by Brad Buxer. I'm also certain that Brad was at least pretty involved with those two tracks. The Mini-boss theme uses two vocal samples from Norman Cook's "Skip to my Loops!", and the track "Money" from Michael's "HIStory: Past, Present and Future, Book I" album uses two samples from that CD for its base drum track, and Brad himself has gone on record saying he worked on the track. It is very based of Jam, and in fact, Jam's original writer, Bruce Swedien (rest in peace) was present during the final recordings at Studio One as an engineer (as he was during most of Jackson's albums, but he could've done more).
