When listening to "scars on this guitar" , I am pretty sure I hear autotune. Right when he says "I find the lights" I hear a robotic pitch shift. I don't know why he would do this, as he can sing it perfectly live, with no pitch issues. Am I imagining it? Also, in 2013, it seems that he may have used a pitch correcting microphone/soundboard filter to fix patchy vocals. Eg, listen to the chorus of this because we can tour version of these days.
