Lost in a Lost World-Moody Blues
Lily of the Midnight Sky-Bruce Cockburn
An American Tune-Paul Simon or Yes
uh mental flatulence gotta go

Some nice responses...
I agree with above: All of Aja, I never tire of "Carry On",
for Chicago it would have to be "Introduction", For Bruce Cockburn it's "Lord of the Starfields" or maybe "Grim Travelers" Agree with Moody's "Lost.."
Also:
1. Stanley Clarke "School Days"
2. RTF "Romantic Warrior"
3. Billy Cobham "Stratus"
4. George Duke "Brazilian Love Affair"
5. Joni Mitchell "Help Me.."
6. I never get tired of hearing Yes - "Roundabout" isn't that pathetic?
7. I never tire of anything Ravel, Debussey, or Mozart
