Rammstein (I’ll occasionally listen to them still), Marilyn Manson, Green Day, Mudvayne, Slipknot, Good Charlotte, Sun 41, Yellowcard, and a bunch of other 90’s nu metal and pop punk emo stuff.
For me it'd have to be some of that late 2000s emo, especially The Used, I tried listening to them again recently and they suck pretty bad.
The most egregious one though would probably be Richard Cheese. I thought he was funny I guess, now the very idea of his music repels me. It's just... shit. True hackery.
I've ended up listening to loads of other music I'd find cringe from my earlier days and finding that I actually still like it. I'd make cases for MCR, Fall Out Boy, Green Day... hell I even listened to some Avenged Sevenfold recently and it was so nostalgic that I enjoyed it. I used to be very dismissive of my old tastes but I've made peace with a lot of it now.
Slipknot quickly lost their appeal and became associated with MMA douchebags who wear Tapout shirts and wear their sunglasses backwards on their skulls.
Ditto Machine Head plus the fact that Rob Flynn became a whining SJW.
I used to like Pink Floyd, Red Hot Chili Peppers, and Queen. These days I realized what steaming pile of garbage those bands are and just best to ignore them.
I’ve been totally jamming to the new Slipknot album and absolutely love it! I’m not ashamed of enjoying them, lol. I’m also reaching back into their older works.
Many bands/performers I just got tired of. Can't really say I 'no longer like' them, because sometimes I can still be in the mood for one.
Exception: Elton John. His work up to and including Captain Fantastic: fantastic. After Cap Fan: I couldn't stand it. When I'd hear him on the radio, I'd turn it off.

Animals is excellent. I'm more of a 'Meddle' girl, but Animals is close.
The Wall is a masterpiece of an album, **** anyone who says otherwise. I love Pink's slow descent into narcissistic fascism, it's terrifying and powerful. Hey You is debatably my favourite Floyd song, other than Echoes.
