What piece of music can you play over & over?

It's a short vignette, but its stops me dead when I hear it, everytime, and I never get tired of it.

Artist: DoMakeSayThink
Piece: Tender History In Rust
Album: You, You're a History In Rust

A Bose radio allows this to be my wake up music
"Applachian Spring Suite" original version for thirteen instruments Keith Clark and the Pacific Symphony Orchestra. Have had it as a wake up call for decades and have yet to tire of it, or turn it off to go back to sleep.

"Hail to the RED SKINS" and "Down with the COWBOYS"

Lately, its been the album "Stationary Traveler" by Camel.

The entire LP's fantastic to these ears, (CD too) but the title song gets me every time.
