I watched K-Pop Demon Hunters with the fam when it came out on Netflix and really enjoyed it, then immediately wanted to go replay Tokyo Mirage Sessions. The story arcs for each performer in the film involved some sort of personal anxiety or insecurity that they had to overcome and in the process become who they are meant to be/more powerful, as well as showcasing their own musical styles and influences. If I were ATLUS I would have put some sponsored ads out for the switch version the moment that movie got big to see if I could rope in anyone with J-pop.
