Most achingly-beautiful music

Ghosthouse, the "7 Year Ache" got me started with what was at the time of that single's release, a country crossover artist. Over the years, she has moved away from the open country sound association. For those who may not be as familiar with Rosie, I suggest starting with "10 Song Demo", which is mostly just Roseanne with her guitar, or other nominal accompanyment. Her voice is beautiful, the self penned lyrics come straight from her heart. It's also great headphone music. Warning: her music tends to be on the darker side; it's certainly no less beautiful for that reason...Highly Recommended.

Swan of Tuonela - Sibelius is the definition of achingly beautiful

"Nothing Compares 2U" by Sinead O Connor

The chorus from "Land of Make Believe" by the Moody Blues

Steve HACKETT'S GUITAR SOLO from "Firth of Fifth"

These come to mind off the cuff.

The space between Celine Dion songs.
