Actually, I think it would be awesome if we could chose what playlists to play island-wide. Imagine going to someone's horror themed island and hearing K.K. Dirge throughout. That would have a completely different vibe than say... 8pm's hourly music would.
you can kind of do this with speakers, ive hidden a bunch of speakers to play music around my shopping area (usually animal city)! they just have to cover the area so that there’s no awkward spots where the music stops. of course it’s a pain to do especially for the whole island.
I think NH's hourly music is the weakest in the series, so being able to switch to past games would be amazing. I'll join your riot if that's what it takes.
