As Nice as Unova's Route (1/2), 3, (6/7/8/9), and Sea Mauville are, I would like to hear a bit more variety with the Route music. Not to mention that Sea Mauville is more often than not, very unfitting for most of what you're doing, at least earlier in the game. There are SOOOOO many beautiful and fun Route tracks that could be playing, like Kanto's Route 1, Route 11, Sinnoh's Route 205, and Kalos's Route 4, just to name a few. But instead we get an unchoosable random choice of the same 4 songs. I really like that you added Specific Town Music, I'm just not sure why you didn't add Vermillion City's.
So I guess what I'm Suggesting is a separate music menu, you know, to check on and off what is playing in the mix each time you enter a new area. I don't know how, or if you can even do that without the servers exploding, but I think it would make this already fantastically crafted nostalgic experience even better.
What music would you like to see added to the game?
