Is it normal to not care about music anymore when you used to be obsessed with

NOPE, My fav album has been Master of Puppets(Metallica 1986) and I CAN'T go on a day without hearing those fast-fingerburning-muted-awesome-kickaSs-motherfckin-riffs

Did you spontaneously start hating ALL music, or just your old favorites? It is completely normal to move on from old favorite songs; i did it when i was younger. And you may return to them when you get older.

People change with every experience so your not doing anything abnormal.

i have a playlist of 28 rap songs i could listen to for 5 hours without stopping.

I know exactly how you feel - If I listen to a good song too many times, I get really sick of it to the point that I can't listen to it anymore.

I immediately thought of depression because that's what happened to me when I became depressed, I stopped caring about things that used to give me a lot of joy. Do you also find yourself withdrawing from people, being more tired, or any other changes?

It happens to me when I listen too much to the same albums.

Really weird you should say that, because the same thing happened to me a few years back. It used to be the biggest part of my life and now it's such a small part.
