Along with the classical composition within the title...
I've listened to:
J.S. Bach - Motet BWV 227 "Jesu, meine Freude" (J.S. Bach Foundation)
[Nikolai Roslavets] Chamber Symphony No.2 (Score-Video)
Chaconne in A major by Giuseppe Antonio Brescianello (with Score)
Jurgen Ganzer: Passacaglia, for Accordion (1994)
Also, try to listen to at least one musical composition from here in this thread (or from the comments below)!
But yeah, this is what I've listened to in this morning thus far.
Enjoy!
(Classical music is good for background music, studying, and reading so give it a shot sometime.)
