Here's my main problem with music.
If a really talented fat ugly guy, with a godlike voice and A++ musical ability, can sing your stuff and people don't like it, it's balls.
I guess what I'm saying, is if you can't replace the pretty, media sculpted figurehead of the band with the guy from the WOW episode of South Park, and still sell records, then you suck.
Music shouldn't be about just making pubescent panties damp. I maintain that the Beatles can't be lumped into this argument as they weren't actually that great looking, and I suggest at some level, most of the fans felt the music was talking to them, not just a simple case of ' I want to ride Ringo's face, so I'll buy Yellow Submarine'.
Look at the people we constantly rip on here at the Escapist, Bieber, Cyrus, Jonas, et al.
Then take a look at the faces of say, Elton John, Aretha Franklin, Meatloaf, Lemmy from Motorhead, Freddie Mercury, none of them typical modern day beauties, but all created vastly more powerful music than the Disney corp or the X Factor.
Sadly, maybe things have changed, as while Michelle McManus, a very large scottish woman who won Pop Idol showed, if you're not the typical 'ideal' look, you won't sell in generic pop.
Note I'm only comparing her to other Pop Idol winners as it'd be unfair to rank her among musicians.
Barry White and Luciano Pavarotti are another example - either of them show up on America's got Talent and they'll get buzzed off in seconds with 'Try weightwatchers and come back next year fat boy'.
It might even be a great thing for music if every band took the Gorillaz approach to music, create some avatars and hide behind them, I'm pretty sure no-one's buying Gorillaz cds purely because they want to get into Murdoch or Noodles' pants.
