Yeah, it's decent... but personally, I couldn't call it the best. In my opinion, the music is kinda hit and miss (not in terms of good or bad, but in terms of outstanding or forgettable) for the early part of the game. Then you hit Coastal Kalos and the town and route themes gradually start to become more memorable. And by the time you hit Mountain Kalos, it seems like every new theme one-ups the last one in terms of sheer awesomeness.
