I can't seem to ignore threads about Bob Dylan's singing smile

I think he has one of the best voices around - not technically perfect of course, but better able to get the song across than anyone else. Some great examples of his different voices:

Lonesome Death of Hattie Carol (early '60's)
Like a Rolling Stone (mid '60's)
I'll Be Your Baby Tonight (late '60's)
Idiot Wind (mid '70's)
Senor (late '70's)
Everything is Broken (late '80's)
Po' boy (early '00's)

I haven't noticed a big difference in his vocal style between the '90's and now....

If the point is to bring the listener into the song, no one is better (imo, of course) smile
