You're right that music is about connecting with the listener. She does not connect with me at all--on any level.
While I will concede that she can convey emotion (more so when facing elimination), she cannot sing on pitch. That is very problematic for me, and I do keep both my ears open. It's not the rock and roll type pitch that doesn't matter so much, either.
There is a place in the entertainment industry for her, but Supernova is not it.
