Yes. 80's electronic music was the height of humanity's musical achievement. The purity of sine waves without all that nasty timbre and resonance is perfection!
I'm assuming it's at least 90% nostalgia. I absolutely love the EPCOT entrance loop too, but I know it's because it takes me back to being a kid and visiting what was easily the best and most impressive theme park ever built. The original pavilions' music loops are similar -- some are better than others but they all give that same feeling.
There are certain stretches in the entrance loop that I think are pretty good regardless of the nostalgia, but a lot of it is not.
