Why JMS is better than all other Maple versions.

Am I the only one who likes this particular one?

You're not alone. That's probably one of my favorite Maple BGMs.

I don't think I could personally single out my favorite track, other than maybe the LudiPQ BGM, but these are my top contenders at all times:

Ellinia field music - this BGM is why I am afk 95% of the time at Where the Forest Ends

(Yeah I'm a sucker for the slow, pretty songs.) I also really like the bgm for Pantheon. It's probably my most recent favorite.
