Remember standing in line for Rocket Rods? I do. Remember watching those short films over and over again as you moved through the switchbacks? Remember being sent down into the smoldering tunnel to wait for another eternity? Remember hearing a faint but annoying tune in that dark place? Oh, I do.
I checked on Youtube and have found it.
YouTube - Rocket Rods Music
It plays as 4:50. Now, from what I remember, it was always extremely faint. The song is a lot worse when you hear it at the original pitch. Who in their right mind authorized this?
Further research reveals that that tune is called "Highways of Tomorrow", and it is deprived from a short tune written by the Sherman Brothers at the end of The Happiest Millionaire called "Detroit", seen here:

Haha, Detroit. Such lyrics surely wouldn't apply to that place today!
Either way, I put it down at the most annoying tune Disney has in the archives, aside from Desert Habitat Kitchen from Horizons!
I think the Imagineers must have been embarrassed as well, since you could only hear it slightly, or maybe guests complained.
