You're not alone fella. On a scale of 1 to 10 I'm -1 excited about this.
That's what I think it'll be too, probably just in the play areas and restaurant. It'll be annoying for guests otherwise.
Interestingly, Splash Landings actually has quite a number of its own songs and themes but are no longer played ANYWHERE in the hotel.
Makes me wonder why they're even bothering with IMAscore. It'll last 2-3 years, then some numpty at Towers will decide it's not appropriate, after that it'll be forever lost in history and 10 years from now we'll all be on here saying "remember that amazing soundtrack which used to play around Enchanted Village?".
SSDD.
