I Walk the Line (Johnny Cash) – 1956

At age 23, Johnny Cash was married to Vivian Liberto, his first wife. Although Johny Cash had a new wife waiting for him at home at home, he encountered many temptations when he was on tour, which led him to write “I Walk the Line.” He wrote it as a declaration of fidelity to his wife.

Cash said that the song was sort of a nudge to himself to keep himself in check. According to its lyrics, he would remain faithful to those who believe and depend on him. The song shows how much he wanted to be the best version of himself.
