Something that really bothers me about Save The World that I know will never be fixed

Mist Monster themes!

The forest OST has one (Of course it does, it was the Original OST after all)
The City, suburbs, industrial, and plains OST have one (Also duh, it's pretty much the main soundtrack)
The lakeside and autumn variant zones OST have one
And the Frostnite zones have one

BUT THE ARID AND HEXLYVANIA ZONES DON'T HAVE ONE!!!
It's a really minor gripe about these zones that just really make their soundtracks feel really incomplete. It's also kind of immersion breaking, having these 'scene setting' ambient pieces being completely ruined by accidently running into a smasher and hearing "BWAAAAAAA BWWWAAAAA". It fits the city, suburb, industrial, and plains zones due to coming from those zones, but it doesn't fit the arid and hexlyvania zones. I'd much rather either zones 'high threat' theme play over the normal mist monster theme as like a bandaid solution
Also technically the tropical zones doesn't have a mist monster theme either, but the tropical zone doesn't really have a soundtrack at all.

And the worst part about this is I know Epic will never add a mist monster theme to these zones. I doubt they'd get whoever composes these tracks to write a single piece to fill this admittedly minor gap.

Although they did add new tracks to dungeons last year…
I'd love to be proven wrong Epic…

Also the Route 99 zone doesn't have a night theme and is just silence. Surely something can be changed to atleast make the 'low threat' theme play regularly rather than having to walking into a crowd of enemies just to get something to play at night.
