I think it's really important that intelligent articles are written on the appeal of this music. I especially like that it pulls apart notions of both a simplistic nostalgic approach to this music, and an approach that only sees these songs as anti-feminist.
Compare that to this piece of rubbish (no surprise) on Pitchfork:One Fad Can Lead To Another
One of the biggest problems I have with the heavyweights of indie music media is they are too goddamn serious... and that title says it all really, with its tone of foreboding. Then you've got terrible lines like: "what is the need for new girl groups who produce albums?" Umm, because they enjoy making them and some of us enjoy hearing them.
Basically the contention seems to be that a revival would be valid, if the process of having professional songwriters write for these groups were revived as well.
First of all, what revival? I suspect these articles are probably the beginning of what will become a self-fulfilling myth of a revival.
