I wholeheartedly agree with the "Aerosmith sucks" guy.
Steven Tyler's singing and his entire schtick are so grating and awful that he ruins the otherwise-decent early records for me. The later stuff is completely irredeemable, of course.
There's a scene in The Decline of Western Civilization II that neatly sums up why I hate Steven Tyler:
Penelope Spheeris asks Steven Tyler and Joe Perry some question about something-or-other. Joe Perry uses his words to answer the question. After that, Steven Tyler just says "YEOW!"
Why open your mouth if you're just going to make a stupid noise?
