If country music had a Mt. Rushmore, Willie Nelson would be one of the first faces carved into its granite walls. Few musicians are as revered by their peers as Nelson for his songwriting, guitar playing, weathered voice and ongoing artistry. 

Today, Nelson turns 82, and the icon shows no signs of slowing down. Last week, he announced his own line of marijuana, Willie's Reserve. In June, he'll release Django and Jimmie, another duets album with Merle Haggard. (The duo famously first paired up in 1983 for Pancho & Lefty.)  One month later, Nelson's annual Fourth of July Picnic, a tradition he started in 1973, will bring artists like Eric Church, Kacey Musgraves, Sturgill Simpson, Leon Russell and many more to the Austin360 Amphitheater in Dripping Springs, Texas. 

In honor of his birthday, Rolling Stone Country asked a number of artists to name their favorite Nelson song. Picking one was a nearly impossible task for most of his disciples, whose selections ranged from the familiar to the obscure.
