These songs sound pretty good in my opinion. I don't think it's shameful. It varies for everyone though...
A lot of Freezepop songs for some reason make me self conscious of those around me from how they sound, Dr. Steel's fanbase is cringy as fuck, and Perfume is such a girly sounding band that even my fairly progressive self finds it uncomfortable, even with "It's American Dad's fault!" as an excuse.
I also purposely picked songs that would serve to soften the blow.
It's been a long time since I had an issue with being ashamed of people knowing I like certain songs. I think I let that go in my early 20's. Had a boyfriend that loved to band shame other people when I was a teenager. I've never understood that mindset.
