I don't see the music for Dragster as "ride music" though; it's an already existing song that the park have just dumped onto the ride. It fits really well, and I personally love that song, but I don't listen to it and think of Dragster. Ride music to me means music that has been specifically written for the ride.
My all time favourite is the soundtrack for Sindbad's Storybook Voyage at Tokyo DisneySea. It's written by Alan Menken who does the music for the Disney films and it's **** ing epic It just keeps building and building as the ride goes on:
