>>86863265There are quite a few ENs better than her at singing like, IRyS, ERB, Mori and Mumei but calling her a bad singer is disingenuous when she sounds excellent on the stage 90% of the time (when it matters the most). The stage is the best evaluation of someone's abilities as a complete package performer.
See the performance I have linked for example. I have always believed that truly bad singers cannot sound good no matter what because they are tone deaf. Bae sounds excellent there even if she may have had to do many takes to get that result. You will never get that level of result by being a bad singer even in a 100 attempts. Bae has talent and potential for being a great singer and her singing has been getting better over time despite no vocal lessons and getting better is part of the idol journey.
