...Welcome To The Pleasuredome. Gotta be the 14 minute album version, NOT the single.
When I lived in Santa Clara, I attended a weekly meeting in San Jose, and got there by taking San Tomas Expressway. I would start the song when I crossed El Camino, and that would be the music for most of the remaining ride.
My favorite part of the song comes around 10:30. "Shooting stars never stop, even when they reach the top...there goes a super nova, what a pushover..."
It really is a brilliantly arranged piece of music, thanks to Trevor Horn. I put it on a mix CD, and if I remember correctly, I followed it with Tears For Fears' "Everybody Wants To Rule The World."
