Heaven Can Wait has been going viral on TikTok for the last 2 years, it's just that all MJ's team has done about it was adding an official audio for it on there with a strangely long title "Heaven Can Wait (If the angels came for me, I'd tell them no)". I mean I kinda get it because what else can you do with it, but it's just kinda...lame.
As for the album itself, (as I mentioned in another thread) they just added the canvas on Spotify, and that's about the first time they have aknowledged Invincible since quite a while lmao. Chances for them taking advantage of it somewhat rising in popularity (e.g. a 25th re-release) are maybe a little bigger right now, especially with the biopic coming out, but them just not doing anything for that album at all is also very likely seeing how they treat other anniversaries outside of Thriller.
