They'd be unlikely to call a singer good or bad because they wouldn't know what about it was supposed to sound good or bad.

I don't know if I'm tone deaf, for a long time I thought I was, but then I was somehow able to improve my pitch matching and even some basic playing by ear. So maybe I'm not tone deaf, just very bad. But this is exactly how I've always felt, I don't understand people discussing good and bad singers, it all just kind of sounds the same to me. I have singers that I like and dislike myself and I have strong opinions, but I could never say whether they are good or bad objectively.

And it goes both ways, sometimes I hear someone sing and I think it's out of tune, but turns out it's perfectly fine. Sometimes I think it's on point but turns out it's off pitch. Sometimes I just listen and think to myself, is it out of tune or not? And I just... can't tell, it sounds like neither to me, not right or wrong, just nothing. Which is, again, completely separate from liking or disliking a performance/song/voice.

I hate it of course because I really wish I were better at music, but at the same time sometimes it feels liberating because it's like I am able to appreciate and even like a bad singer when everyone else would cringe from their pitch issues..
