Popular music: a significant trend toward narcissism and hostility

Неоднократно подмечено, что раньше трава была зеленее музыка была душевнее :)
Теперь это подтверждено научными исследованиями: Study: Narcissism On Rise In Pop Lyrics
Как правильно формулирует Paul Sullivan в Metro News:

Thirty years ago, everyone was having a good time.. racial harmony .. and togetherness.
These days, forget about peace and love, it’s just about me. No one is feeling the love much these days, unless it’s love of self.
It’s hard to believe things can change so much in a single generation, but guess what happens when the only subject taught in school is self-esteem?
Ergo: Pop self-esteem sells. I don’t need a scientist to tell me that.
