Bob Dylan has been named in a music magazine poll as the number one rock genius of all time.
The 61-year-old folk legend came first in Blender magazine's list of 50 artists that includes controversial US rapper Eminem and the late reggae musician Bob Marley.
The late Beatle John Lennon was second on the list, but his fellow former band-mate Paul McCartney only polled fifteenth.
Chuck Berry was at number three.
