She can't sing and isn't dedicated to her craft enough to improve? Let's not forget Weeknd used to be terrible live. He's still not some great singer outside the studio, but he has greatly improved and can put on a good show now. SZA is more than capable of improving...so why isn't it happening.
Granted, stans can always find a recent clip of her singing well live but doesn't that further drive home the point that she has no excuse to be ASS in other recent clips? Consistency. It matters. She's on the verge of blowing the fukk up...yet I just don't get the impression she wants it, and instead she'll sink into depression and not really "try" because "trying" and failing hurts more. I hope I'm wrong.
