If you had lived and witnessed Michal Jackson mania as for the 80s, you'd understand that the Cascio songs are shitty tracks for someone like THE Michael Jackson and that it doesn't do him ANY favor in releasing them in the state they're released. If they want to keep on with MJ's legacy, they should not touch a little bit what the master has crafted, but release them the way he left it.
But you come inhere with your judgments of someone who has never known the excitment before "Thriller", "Bad", "Dangerous",... were released and you give credit to your excitment before "Michael" was released erecting the Cascio songs such as "Monster" to the level that beyond any doubt is far, far, far away from reaching Michael's ankle of legacy.
There is no single proof Michael ever did anything for those songs, and if Michael was really happy about them he'd at least include your "Monster" song on This Is It concert as a new song or something. Instead he planned to sing other songs (none of which being a Cascio song). Those songs simply seem to be nonexistent in Michael's life.
Do you actually realize the meaning of NO SINGLE trace? Not a scratch on a sheet of paper, not a scratch of music sheets, not a phone call about the songs, not a video, not a worktape, not a single alternative take, nothing, complete VOID. That's what the Estate has provided to the fans as a proof:
VOID!
Yeah, excuse my doubts about the authenticity. To me official seal doesn't mean "the truth" seal.
