I don't know how to speak music, but I'll try. I think the dissonant notes together with i believe micro tonal pitch bending (maybe I don't know i have bad pitch) in the original better illustrate the discomfort of Trent very poetically.
Also Cash sensoring the original lyrics is okay, but it doesn't deliver has hard.
Don't get me wrong, both versions are beautiful, and this is just nit picking
I think that Cash's slow delivery, acoustic guitar, and deep, raspy voice, better delivers the despair and loneliness of the song.
