Bello Nock's act was one of the most impressive things I've ever seen, and him not even being in the top 8 sounds highly suspect. It's the first time I genuinely believe all the talk about these shows being blatantly rigged, to be frank.
And yeah, singers always advancing is boring, but it makes sense from a busness perspective. They make way more money off of singers, since they have to sign with their record label etc.
