Released in 1956, "Get Rhythm" is an upbeat number by Johnny Cash with positive lyrics speaking of a happy shoe-shine boy. While the song is classic, inimitable Cash, it would quickly become overshadowed by its b-side, "I Walk the Line." A peculiar song that changes key between each verse and has no chorus, "I Walk the Line" would become the song Cash is best known for, a tale of pledged fidelity with lyrical undertones implying even deeper meaning. Rolling Stone magazine ranked the song at #30 in their 2004 list of the 500 greatest songs of all time. A: Get Rhythm B: I Walk The Line
