A lot of them, yes. You just have to listen closely.
I'm not saying she can't sing, her vocals are good but they are helped IMMENSELY by a small level of autotune. In theory if she polished her technique just a fair bit more, she could be great, consistently.
If you didn't know, the entire MTV Unplugged album is edited.
Also she used to use live pitch correction during CDT.Her vocals sounded a bit plastic-y... imo they
would've sounded just as good without it.
Other performances that were autotuned are TOTGA @ X Factor, Firework @ VSFS, etc. A lot of performances from TD era.
This era she's completely eliminated the autotune from PWT and most of her performances but that doesn't stop some networks from editing her vocals afterwards (U-Express and Mod Club Acoustic for example.)
Anyway she's improved a bunch... like her Crossroads episode wasn't edited and she sounded amazing. She is getting more confident with herself and I love that it's genuine and not just reflected in her music. Her lesser makeup etc all reflect that.
I never hear Roar anymore since my local AC/HAC stations prefer playing Brave. I feel like her recurrent airplay is being sabotaged tbh. (the paranoia).
