Most achingly-beautiful music

The Songs of Crazy Horse by J. D. Blackfoot. Have loved it for almost thirty years.

John Williams "Cavatina", the classical guitar theme from the movie "The Deerhunter" with Robert De Niro. Heard it 20 years ago, still haunts me to this day.

#1 Tchaikovsky's Symp. No. 5 in E Minor (Mstislav Rostropovich conducting the London Philharmonic is exemplary)

#2 Mozart's Sinfonia Concertante for Violin and Viola (as performed by Henryk Szeryng and Bruno Giuranna with the New Philharmonia directed by Alexander Gibson)

#3 Dire Strait's Brothers in Arms

Patti Smith Gone Again in particular My Madrigal. If this doesn't tear your heart out you have to be dead.

Mozart Requiem - Lacrimosa.
