For me, it's Bob Seger. I hate myself for how much I love Hollywood Nights. Also, I feel like Seger was probably just another one of those barely talented white boys who made it big because he literally stole a ton of stuff (melodies, basslines, hell even lyrics) from truly talented Jazz, R&B, and Blues musicians...but maybe I'm wrong. Just a gut feeling
As I get older, I find myself less and less concerned about my music taste being cool. I don't think it's worth ever hating yourself for liking music of any kind. I'm not afraid to admit that I find a lot of 90s boy-band songs rather catchy. Not trying to listen to them all the time, but I feel no need to maintain a front of dislike for them anymore.
So, with that said: I think boomers had some pretty good music. Yes, a lot of it is ripped off, and it's definitely worth exploring the source material the white artists were drawing from, but that doesn't make it shitty music.
