It provided such happy music as you rode along!
I mean, who could possibly be depressed or feel hopeless while listening to that pleasant, soothing, "life is great" music it played throughout the trip? It was just so amazingly optimistic and placid.
On the other hand, I heard some music that I believe was tied to the Rocket Rods (like, queue music or something - I could be way wrong) and it sounded disjointed, dischordand and disturbing. Maybe the ride was thrilling and had a neat "take-off" sound, and I'm sure it was popular. Never rode on it myself.
I'm not saying they should bring the Peoplemover back, I'm just saying it had an optimistic and soothing spirit that was undeniable, and had it been utilized properly it could have stood the test of time.
