The Most Beautiful Song You've Ever Heard?

[civiclx]

This would be better fitted in the music forum and this could even go in the "on your mind" thread but I'm starting a new thread damn it

Can anyone actually say what they think is the most beautiful song they've ever heard? I will never be able to pick my absolute number one but some songs in contention would be

Coldplay
Yellow
The Scientist (The song that made me discover them)
Warning Sign

John Mayer
Gravity

Rob Thomas
Ever The Same (This one is close to the top)

Counting Crows
A Long December

There's definitely some others that would be on the list. Right now I'm listening to Imagine Dragons' Demons on iTunes and it's a great song.
For harder rock songs, I'd give a nod to GNR's cover of Knockin' On Heaven's Door and it could be Pearl Jam's Yellow Ledbetter that occupies the top spot for beautiful rock songs. Eddie Vedder sounds just incredible on that song.

What do you guys have?

Edit: How could I forget
Hootie & The Blowfish
Not Even The Trees

Sarah McLachlan
Angel
