When I was 15 I listened to a lot of metal and my parents found it gross obviously. Idiotically I said to myself I'll never be like that, I will try to understand every genre of music. Yeah, sure. I'm not even old and I'm already like them. Fucking skrillex and nicky minaj.
Music went downhill with the invention of MTV then nosedived with the invention of auto-tune. That isn't even debatable. Before MTV, you actually needed to be able to play instruments and sing to get featured on radio.
Nigga please, I hate rap, but compare Lil Wayne to early 90s rap and it's two different worlds. Or compare modern metal to Metallica, AC/DC, Iron Maiden or whatever your favorite bands are. There's a reason those dinosaurs still sell out stadiums, it's because they can play.
Today, you only need tits and ass to sell.
