The Voice has an uncanny knack of putting on people who've had previous fame just so they can be humiliated when none of the judges turn around. I think the only singer with previous experience to get through the blind auditions was the woman from 5 Star in the previous series.
Tyler James had had 2 top 30 hits & was a finalist last year! Not not true that all ex-pop stars are humiliated.
I think this does rather prove the ageism of the music biz though. It doesnt matter if theyre turned the other way, an experienced musician would be able to spot a more "mature" voice from a teenager who's learning the ropes.
