Gonna need you to sit down for this, poobledoodle. I've never heard a single Bob Dylan song in my entire life. Don't even know what the dood looks like. I'm so sorry (I'm not sorry at all)
To that first point, fair enough! That being said, nope and nope to 1 and 3. So I've heard, as far as I am aware, 1 Bob Doolan song. I didn't have enough friends for Rock Band, but THANKS for bringing up those tender memories, Ref, jesus. Maybe I didn't have any friends because I barely know who Bob Dylan is
What about "All Along the Watchtower"? "Knocking on Heaven's Door"? "I Shot the Sheriff"? Dylan songs, all, even if made popular by others. There are many others, too, that I'm sure you've come across without knowing it. If you've seen the Big Lebowski (and really, everyone should have by now), Dylan did the theme to that movie (I think it's called "The Man in Me").
