Acoustic gtrs in the intro are out of tune... but, hell, I'm realizing as I listen that this doesn't matter. At :17 when the electric comes in it has a beautiful effect. And at :34 when the vocal enters it gets even better. Sorry, I just can't be objective about the song any more because I like it too much.
...even with a few autotune artifacts on the vocal that might be better made more subtle (guessing).
Hell, who cares. Great tune. Too Beautiful, really... an accurate title.
