I’m beginning to suspect that nostalgia is a form of brain rot.
I've struggled hard to do it, but in my forties I'm still listening to new music and watching new media. I want to go out like John Peel, listening to good new music until the day I die.
I still listen to and watch a lot of old stuff, but I really try not to make it my main entree.
I honestly think if you're my age (mid forties) and you're still listening to music exclusively from the 90's it's gotta count as some type of arrested development.
