See, I was watching this video, and this song... Its SO beautiful. And I love it. But guess what? I don't know the name of it. If you know it, or could help me, this would be appreciated so much. And you don't have to watch the video, I kinda advise you not to unless you into that kinda stuff... Anyways. Please help.

I'll offer some kinda prize if you can tell me the name, since I've spent a day so far looking for the song name and got nothing. >.>.... Here's the URL to the video I found the song in:
