She doesn't have the talent to make a living as a singer even on a local level IMO and the Judges knew that from the beginning.
It's sometimes less about talent than it is about
attitude. I had a really great teacher who turned out a lot of successful artists, tell us all the time, "Attitude monitors talent."
We've all seen some really talented, super successful stars kill their careers (or even themselves,) due to their attitude: either about their career, how they deal with other people, or their attitude in their personal lives. Whitney Houston for one.
Someone on AI who took herself out of the running with her attitude was the girl who was partnered up with Nutsa for the duet, who acted all victimy and openly threw Nutsa under a bus, (even though Nutsa was selfish.) I don't remember that girl's voice, but you could tell that the judges wrote her off for her attitude.
And I kind of hesitate to mention these two people, as I don't want to derail this thread and we go way off topic, (so let's all stay on topic,) but there's the Sussexes, Harry & Meghan. I had such hope for them at the beginning. That Harry could continue to do great work, bringing international attention to great causes like Diana did after leaving the royal family, bring attention to the leftover landmine after wars. But, instead, the Sussexes attitudes have been nothing but whiny, complaining and being VICTIMS and keeping the attention on
themselves.
For people whose attitudes helped or made their careers: it was thought that Robert Downey Jr. had ended his career when he went to prison & rehab for drug charges. But, he's kept himself clean & sober and has made a successful comeback due to his attitude.
At the other end of the spectrum, we've seen people who have what would be considered moderate
singing talent have successful careers. Like Cyndi Lauper and Madonna would never have made it on AI for their voices, yet they've proven with their attitudes and fortitude, that Madonna had imaginative performance ability and sticking power (for a while,) and Cyndi had outrageousness and later comeback power. Cyndi's talent is actually in her songwriting. She could have thought to herself that she was only an 80's star and remained in has-been semi-obscurity. Instead, she wrote and won the Tony award for
Kinky Boots and has proven she is a devoted activist for the LGBTQ+community and outliers in general. She's going to stick around.
Attitude monitors talent. Or, put another way: Attitude
monitors talent.
