And don't be all, "none! lolololol!"
Also, don't say any of the KROCK hits from Appetite for Destruction, because that will prove you are a dumb rube. If you must name something from Appetite, at least say Mr. Brownstone.
The guitar-worshipping child in me can't say anything but "November Rain," but the current rock and roll pragmatist in me thinks maybe "Knockin' On Heaven's Door."
("No, but SkinBen, the Dylan version is so much better!" No it isn't. The Dylan version of anything is pretty much always made better by the covers. Know why? Dylan wrote great skeletons of songs, but that's it.)
I might also be swayed to say "Civil War." Holy crap. I think I'm gonna amend my answer to that. You know why? Because what....we've got here, is.............................a failure...........to communicate.
