Most Beautiful Song I’ve ever heard.

OK, soft moment coming up.
I was trailing through my hard drives music the other night and on the Ministry Of Sound Chilled album I found “Barber’s Adagio for Strings – William Orbit”.
I wasn’t expecting this kind of song as I have never gone through the entire album. I have to say I was pleasantly surprised.
I think I may of heard it elsewhere but it had an amazing effect on me. It immediately put me in a calm and happy mood, something I haven't felt in a while.
A good classical song has always made me sit back and listen, some I will loose myself in. This is one of those songs.
I know that many of you won't agree, I doubt any of my friends will share my view on this either.
However I seriously believe it is the most beautiful song I have ever heard.
