What sends shivers down your spine when you play it on your system?

The 1st movement of Mahler 9.
Rachmaninoff “The Bells” 1st and 2nd movements (I have about 20 different versions of the piece.)
Brahms Cello Sonata #2, 4th movement.
Schubert Piano Sonata in Bb. D.960. (And much other Schubert.)
Anything by Eva Cassidy (Can’t help but tear up when she sings.)

Agree on “Musical Box”.  The finale of Suppers Ready is another. 

@dweller Totally agree - those chimes are amazing.@schubert Yes, such a beautiful tone poem. Absolutely sublime.

Art Pepper “Patricia” long version
Brubdck Quartet “Blue Rhondo” carnigie hall version 
John Coletrain “Summertime”
Sonny Stitt “Cleveland Blues”
Dr Lonnie Smith  “Backtrack”
