Friends, family and fans of Johnny Cash will be honoring the legend's 80th birthday today (Feb. 26). The 'Man in Black' had a career that lasted nearly 50 years, from 1955 until his death in September of 2003. He released over 50 studio albums, 150 singles and scored over a dozen No. 1 hits.

But which song is the best Johnny Cash song?
