Beautiful. I wish I could play this game for the first time again. The way they used this song in the game was perfect. From the opening to the end. I can't praise this game enough. 

Edit- The full version with the guitar duet is really good too

Bioshock Infinite is the first video game to have made me cry in 13 years (last time was Final Fantasy 8, when I was ten) and it did it in the first half an hour.

That song, those candles, the water... They got to me.

Beautiful, just beautiful... Gives me shivers.
