Okay, I might be unpopular with this statement, but I sang in a church choir and in a gospel group,…and quite honestly there were many singers in our local churches as good or even better than Susan.

I think this is just one huge marketing scam to get more viewers. Making a swan out of an ugly duckling is show business. They are using this poor woman, and I felt their reaction to her in the show was pure acting. No way they could have been surprised. They preview all the candidates before they go on stage.
