Willie Nelson (1) -

Country music legend whose iconic public image has often been as widely reputed as his music - Nelson's environmental efforts (including founding his own biofuel company) and his political endeavours have earned him a popular image among the American people. The 36 albums and countless recordings contributing to Nelson's legacy as a songwriter cannot be summed up, but it is fair to say that very few people have had as great an influence on American music as him.
