It's like some people are proud of being out of touch with modern pop culture and they have to make sure the world knows just how out of touch and cool they are, it's willful ignorance, that is nothing to be proud of it's fucking embarrassing.
I don't get it, it takes one minute for a poster to look on Google and find out if they don't know who somebody is (and who knows, you might even end up being a fan!) rather than post their ignorance on a forum. There must be some cache attached in their mind that doesn't exist outside, like those who like to post 'first!'.
I love 80s electro/early 90s hip hop - it's about 30% of my vinyl collection, but posting how newer music just doesn't hold a candle to it is pretty gross and closed minded. I guess that's always happened though - from acoustic to electric, from keyboards to synths, from 4-track to sampling, always somebody whining that 'the old ways are better!' and that music should never evolve.
The good thing is, you can still listen to your old, favourite music and ignore everything that's new, but keep it to yourself, nobody cares.
