Well, yeah, if someone has zero idea and hears some player pick off notes at blazing speed, and with crazy precision and attack, it conceivably does sound like a mess of brain-frying audio.
Its the kind of thing people have to mature into, when I was younger, my drummer friend would play songs from bands like Nile, or other similar bands where the drummers were going so fast I had no idea what was going on and thought it sounded like shit.
As I matured, and my playing matured, suddenly not only could I understand what was going on, I actually started to really enjoy and appreciate it.
