I made a thread recently about this in relation to Epic Universe specifically, but I figured it's an important subject and I have many more thoughts about this stuff outside of Epic, so here's a general thread.
I hadn't seen it chronicled anywhere, but I wanted to talk about the Dinosaur ride area loop. The old CtE area loop was preserved through an old Disney Parks CD, but there doesn't seem to be any chat about the different Dinosaur-era loop. It got me worried that we could potentially lose access to a new original park loop that went under the radar.
After some digging, turns out they just played the film score from the film Dinosaur on loop. It's a boring answer, but it's a comforting one.
