I much prefer the music around The Welcoming to that! It's a bit depressing and forgettable, although if it is going to be the ride's soundtrack I'm sure there'll be more to it
Whilst I agree here, does the soundtrack really have to have a sort of tune or "memorability" to it? Personally I believe that as long as it fits the theme well and creates a good atmosphere, the music has done it's job. In certain cases (ie. The Smiler), this obviously doesn't apply.
The soundtrack is highly likely to be part of the final soundtrack for the ride imo, but that's way too short of a segment for me to take a guess as to if it's IMAscore or not - it could easily be someone else.
