There's an MJ song called "Monster" (unrelated to the one that appeared on the Michael album). It was made in 1998 for the Invincible album, produced by Brad Buxer, Michael Prince and C.J. Devillar. It's unfinished, consisting of a chorus/hook
"You created a monster, you're a monster, you're an animal, that crawls at night".
The producers have said that it's the most complex song he made, with over 100+ tracks. C.J. Devillar spoke about it in depth in the 54 Episode of MJCast where he described that (he) might have recorded 40 tracks with stack vocals with verses and a bridge
"Maybe had some sketeal ideas of that, but I know we practically filled it".
There was an orchestra laid out, huge amount of percussion [...] It was very experimental. It sounded like a very personal Michael Jackson song to me. It was like one of his SGT Pepper songs, that he went kind of 'art' instead of hitting us with 'pop'. He reached down to a different place with this song, it's more challenging to listen to."
