It isn't that much of a stupid question... It's clearly not asking if Gaga was the first pop musician you ever listened to, but rather were you a proper Pop Music Fan prior to Lady Gagas emergence...
IE If this said Katy Perry, I would answer No, despite the fact that I did in fact listen to pop music radio before her emergence - it's just that I didn't particularly care who or what sung what or what the videos were, etc etc back then.
Most of the monsters answering Yes are clearly lying though.

Either that, or they're just acting like fools in arguments about who's copying who for no damn reason.
