8. I Walk The Line — Johnny Cash (1956)
Johnny Cash is an integral element in the fabric of true Americana. ‘I Walk The Line’ is arguably his most famous track. It sold over 2 million copies, and was No. 1 on the Billboard charts. Cash’s Arkansas twang totally shines as a complementary to Cash’s guitar strumming. Due to its beautiful simplicity, many regard it as the best rock song ever created.
