I honestly don't really know. I mean, Mouse is right when he says she's more fit than she was in her early 20s, but I don't know. Because I watch videos of Katy playing with her guitar and i cry due to her vocals
But when I listen to her when she's dancing or moving around a lot, it's not as good, sometimes even off tune
And I hate to say that, it's even brought me anxiety before; telling myself she isn't good, believing it, and freaking out because I feel like it's mandatory that I stop being a Katycat, which is why I freak out, because I KNOW I love her, just no matter what I'll tell myself "Oh remember that performance where she was off tune?" and I freak out. It also doesn't help my anxiety to read comments saying "Talentless" and "She's never good" or whatever
But it doesn't affect as much as it did before, because I'm beginning to accept again that Katy is an angel with her voice. Anyway, I think I went a bit off topic
My opinion? I don't know. I don't know why some of her performances are pitch perfect, and why some are off tune. But do I think dancing affects her voice? Eh. But then that leaves me the question, if it's not the dancing, what is it?
