I'm trying to think of a phrase that's less melodramatic than "heartbreakingly beautiful" while still being accurate, but no luck.

Wow. That was wonderful.
I may respectfully suggest "lyrically haunting".

That definitely works

(I've decided to make a deliberate effort to listen to new music, and this is from the first batch. I've got a tentative schedule and a growing list of musicians/albums to listen to.)
