The Blower’s Daughter by Damien Rice is a favourite of mine.
The Ecstasy of Gold - Ennio Morricone
One of my all time favorites is the first opening theme of the anime Ghost in the Shell: Stand Alone Complex
The Letter That Never Came or Eva Cassidy’s rendition of Somewhere Over The Rainbow.
Rivers of Light soundtrack from Disney’s Animal Kingdom
I’m not sure what I think the most beautiful song I’ve ever heard is, but I know my mind usually goes to two songs:
Pastoral, by a man who went by the name of Moondog. He was a legendary blind composer, playing on the streets of New York City between the late '40s through to the early '70s.
He’s kind of a “your favorite musician’s favorite musician’s favorite musician” figure, and was known to play several instruments of his own invention (one of which I believe is used in this song, but I’m not sure). This is a very minimal song, but beauty doesn’t always demand grandeur.
Second would be Slips Away by Peter Silberman, the lead singer of a band called The Antlers (who also have a bunch of really moving tracks in their discography).
This one is also very simple, and quite melancholy, but I think it says all that needs saying. If I have a funeral when I pass, I’d really like this to be played at it.
The Greatest Show On Earth by Nightwish. It’s about 17 minutes long, plus an epilogue narrated by Richard Dawkins.
Hard to choose one, but Metallica - Fade to Black.
Always thought “Kiss from a Rose” by Seal was very beautiful.
Ill mind of hopsin 7. It’s about his journey to find God, only to hear nothing and return to his life of enjoying things but acknowledging that if God is there and wanted us to live different, then he wants God to tell us this directly instead of being cryptic.
I always loved the Forrest Gump intro theme.
Fisted and Forgotten by Glass Casket
the lark ascending by vaughan williams
Merzbow, discography.
Samson by Regina Spektor has to be up there for me.
