Not a ride song, but anytime I hear the Voices of Liberty I get the warm fuzzies & a smile on my face. Some of the best entertainment at WDW. As for ride songs, I'll vote for 'Grim Grinning Ghosts" as well. Used throughout the ride, it morphs from a creepy, slow, dirge at the beginning of the ride to a frenzied party tune during the 'swinging wake'. Fun!
