Bob Dylan; the rarest exception to having a crappy voice yet writing songs that defined your decade. Put him up next to the Beatles and the Stones and above everyone else, he belongs there in praise.
I read Bob Dylan and Johnny Cash had a lot of respect for one another too. I actually prefer Dylan's "it ain't me babe" covered by Johnny Cash and June Carter instead.
Holy crap did Dylan write the best lyrics.......like the God of lyrics if you could have a God of lyrics.
