I was too young to mourn the original losses of EPCOT Center, but SpectroMagic is one of those losses that stings. RoE and the Great Movie Ride are two others. These three experiences collectively embodied the soul of their parks during their respective eras, and their relacements (or lack thereof) feel hollow in comparison.
Didn't even stop to watch it that often, but the elegant waltz soundtrack was so uniquely fitting to MK. It screamed, "this is a special night" no matter how frequently it played. While MK's fireworks shows have consistently stepped it up, I don't think a single parade has suited the park like SpectroMagic, and I hope if the park ever receives a nighttime parade again, the soundtrack will pay homage to and sample it somehow. As much as it works for Paint the Night or MSEP, not every parade needs a modern, high-energy, electric feel.
