Katy's never delivered good vocals for any of her uptempo live performances. Ever. Said without hyperbole.
A few of her acoustics were decent but even those are hit and miss. Not a single one of her performances justifies her career as a singer though.
So stan up to the point of buying her videos, singles, albums, merch but paying to see her live is where any self-respecting fan should draw the line. Her shows are overstuffed with costumes, choreography, stunts, sets, backup dancers/singers for a reason!
