We're dealing with hordes of people nowadays who don't even know. Remember a few years ago when tons complimented Kanye West for giving that unknown, Paula McCartney, a chance in that duet?
There was a guy here a year ago who said AC/DC wasn't a Metal band.
He's not alone, as Zeppelin isn't even considered one by many anymore, and they were only the biggest Heavy Metal band there was. And of course Jimi Hendrix didn't start it, Black Sabbath did because reasons.
Can't wait for a generation or two when they're saying Quiet Riot was the first Metal band.
