Nobody's saying you cannot like Green Day, Avril Lavigne or Good Charlotte. It's a matter of (bad) taste: you can like whatever you want. The fact is that this music is being labeled as punk, while it has nothing to do with real punk music, first of all because of the message. Punk music has a kind of message that you can dislike, but that is not the kind of trite message of all these pseudo-angsty teenagers, that like to repeat all day: "I hate you! I'm so fucked up, leave me alone!". Jesus Christ, is that punk? And is it even more punk-style to dress up like billions of other teenagers? At the time punk was born, being punk meant being "different" not in a fashionable way... And punk music was so powerful because punk bands were involved, politically and socially. Now, saying governements suck ain't a very deep analysis, but still the greatest part of new punkish bands are unable to say something so banal. And if they say it, they don't dare to explain reasons and consequences. They can only repeat "This sucks, you suck, I suck, suck suck suck!"
There's more polical accusation in country/folk music than in those punk wannabes, who in fact are more politically correct than anybody else on this planet. I bet even a Smurf could be less polically correct than them! And I'm sure that if thse punkish kids can manage to dress a little better for a day or two, the Pope could even decide to invite them
Spears is terrible as a singer, but at least you know what you have to expect from one of her albums. Aguilera is even more irritating than Spears IMO, because she even tried to sound clever in some songs (I mean, her producers wanted her to sound clever), which is utterly disgusting. And there are persons around, not only kids (which is scary!), who are saying "Oh, listen to Aguilera! She's very clever in this song, and sincere!". Please...
