Why: Willie Nelson is a clear winner when it comes to the letter 'N.' His nearly 60-year career includes numerous chart-topping hits, but not just songs that reached No. 1 and faded away. Cuts like 'On the Road Again,' 'Blue Eyes Crying in the Rain' and 'Always on My Mind' are immortal country classics. Then of course there's his work with the Highwaymen, and his numerous duet partners including Waylon Jennings... Needless to say, Nelson is an all-time legend.

Honorable Mention: Joe Nichols
