Why did the coffee shop play so many hours of Bob Dylan today?

Three hours of Bob Dylan is too many hours of Bob Dylan for me.  It is really too many hours of Bob Dylan for anyone, I suspect.

It's like water torture, except instead of drops of water on your head, it's a constant incisive whine needling at your eardrums.  So it's really entirely unlike water torture, except in its effects.

So...I'll cry "uncle."  What do you need know?
