What's the deal with Dylan?

Ok, guess no one missed out on the fact that Bob Dylan is turning 70 today. I gotta admit that he have written some good songs, but that's about it. Practically every artist do the songs better than him. He can't sing and he shouldn't be allowed to touch that harmonica of his. I wouldn't attend one of his gigs even if I got payed. I may only be 36, but in this case I feel like a grumpy old man. Dylan is one of those artists that, if you are critic, you aren't allowed to criticize. I say fuck it! But like I said, he's a decent song writer, so don't shoot me.
