I just tried the original game on scummvm, and the difference in imuse is pretty huge. The original has extremely good transitions as you move between areas in Woodtick. The new version seems to use rather straightforward crossfades in classic and special edition. On the other hand, I tested how Curse implements the dynamic music system in the barber shop which has a similar music theme as Woodtick, and it's actually even worse there. There's no transition at all, it just snaps from tune to tune with zero transition.
So in the defense of Monkey 2 remake, it seem that not even LucasArts could create a good imuse system to work with wave music back when they were top of their game.
Although, the one inexcusable thing with the music in the Monkey 2 remake is the lack of MT-32 music. The difference between adlib or general midi, and the MT-32 music is gigantic and it's a huge shame they didn't record the MT-32 music for the classic version. One thing I'm a little worried about is that the new arrangements might be based on the general midi version, and not the MT-32 version.
But well, in the grand scheme of things it's still a minor issue. I'm having a lot of fun with the remake and I love the new artwork they've made and the voice acting.
