I think one of the biggest issues with music at towers is the crap speakers or systems in place. Take Galactica it has a good soundtrack, but most of the speakers around the ride and queue are broken/off. There’s one old Bose speaker half way through the queue which works for the whole queue line, which is so loud you can hear it from the car parks. Half the time the audio in the station is off, and even those new speakers they added around the ride area when it became galactica often don’t work properly.
You have other areas the same, you’ll often find the speakers outside the Welcom-inn off, making that area silent. So I don’t know if that’s just it being turned off, either too quiet or just broken.
So there’s no point spending 1000s on top audio when you have awful cheap speakers.
Towers/ents answer now is to just fill a are with as many speakers as possible, Mutiny Bay now probably contains 30+ speakers all blasting their music out, which is great, but I’m not sure how much thought is actually put in to these speakers and the locations, rather than just putting them all over an area to fill the area with music, rather than directing the speakers in to the right areas of the park. This then often leads to sound clashes, X sector is the best example, stand near the bottom and you’ll get a mixture of the Smiler blasting out with the speakers near the shop, Oblivion blasting out around the drop and then Spinjam blasting pop music out. Last season was worse when you add Enterprise in to the mix.
