I think this track uses two guitars played back over each other. You can replicate this effect
by fingerpicking with an alternate thumb pattern.
[Verse 1]
C#m F#m
Love is a razor
B G#
It's cold and it's sharp
C#m F#m
And it's cutting out your heart
B G#
The glow in the dark
C#m F#m
It's selling wine
B G#
And it's topping the charts
[Refrain]
C#m C#m/B A G#
I don't know where I stop and it starts
[Verse 2]
C#m F#m
Love is a razor
B G#
So much stronger than me
C#m F#m
It sliced up the eraser
B G#
I was saving for your memory
C#m F#m
It's cutting me bad
B G#
And it's taking its time
[Refrain]
C#m C#m/B A G#
But it won't give back any of mine
[Outro]
C#m F#m B G# (repeat until end)
