Dylan listeners will know that Like a Rolling Stone, a long song in comparison to the commonly heard music, is not even in the top of really long Dylan songs. It actually comes in at 56. The top ten are as follows (and yes, I realize that Last Thoughts on Woody Guthrie is not actually a song so I'll include an extra; Last Thoughts was, however, performed once):
