Bob Dylan changed everything. The uncontested poet laureate of the rock and roll era and (arguably but likely) the greatest singer/songwriter of modern times, Dylan has entertained and intrigued the world for half a century. He has plugged in, dropped out and returned to tell the tales, so we've collected his classic songs, as well as those of his collaborators, colleagues and the legions that he has inspired on one radio station. This is Bob Dylan: DNA.
