So The DJ - Musical Rares we all know is replaced in The first remake with DJon...

The reason he ain't in this remake is because they chouldn't own him so they wanted to make their own Musical Rares and decided to make him a puppet to avoid copyright with Musical's Pizza Party World. But don't worry DJ - Musical Rares is in this remake in Minigame form, and if there will be a remake of AFTF, I promise Musical Rares whould be in it as well DJ Playtime.

Because it's lore related
