It's being young, and being part of the youth movement, it's exciting, things are new, you're young, strong, healthy, it's easy to make friends in your teens and 20's, you're not worried about responsibilities, the future is wide open...
The musician that are famous are older than you, you can look up to them, they're doing cool things, they're so cool!
Then 30 hits you like a fucking sledgehammer, you're an adult, you have to be serious about work, get shit done, no more fucking around.
Then you see all these kids, running around thinking they're the shit, they're stupid naive, little twats with faggot hairdos, and even the hot girls are dumb kardashian bitches, they think they're cool cause they listen to dubstep but they're just brainwashed corporate zombies paying 600 a ticket to see ultra in miami, when you saw juan atkins for free in a basement party in 1997, and it was cool as fuck. Those dubstep kinds never even heard of juan atkins and they look at you weird when you try to educate the little cunts that he invented the music they like 30 years ago, and they're not new or original, they're just more flamboyant and cheesier and they're not even enjoying the music they're just taking pics for their status updates so people KNOW they went there, but they don't know the names of any of the fucking songs.
Honestly the 90's weren't THAT great, but there's was a mystic to it. The 80's even more mystic, and 70's just crazy mystic. Now every fucking thing anyone does is documented, updated, filed away. And song can be had at a moments notice, it's not special when it comes on the radio, or you have to pay money to buy it and invite your friends over to listen and it's a big deal.
