Well, I could agree with the songwriter part. As for singing, the guy can't carry a tune in a bucket!!
Anyone who doesn't agree doesn't know music. :-)
Well, I know singing! And I say he comes across as nearly tone-deaf. I like his stuff when covered by people who really know how to sing... or at least carry a tune!
Jimi Hendrix, who early on rarely sang vocals, said if Bob Dylan can sing vocals, anyone can.
Like Neil Young. If he hit the right note he’d total it.
Oddly compelling and beautiful, taken on the whole though. Wouldn’t be right without that cracking voice and the sort of sour harmonies.
