Exactly the point, the fact anyone thinks of an artist or band is "shite" is utterly irrelevant, if they have millions of followers they're not "shite" to them.
As a FOC I'm not struck on the Stones or the Beatles but I'd never call them shite, they had a huge influence on music, I guess Oasis have inspired a whole generation of Musicians. I think they're brilliant but I've always loved proper guitar inspired bands
I grew up with Punk Rock, still have a lot on my play list but I also have Springsteen, Al Green, Paul Heaton (going Monday), Frank Sinatra, a bit of Brass band and loads of Indie. However each to their own, from Rap to Opera who's to say its "shite"
