I can sympathize with Christina's reaction to Tony Lucca. 99 Problems is a great song but it's also straight up misogynist. And to be fair, Tony Lucca does suck and probably only got as far as he did because he was a Mouseketeer.
Actually, that was back when one singer per coach was guaranteed to make the final show and in the semifinals the coaches gave a number vote for their final two singers. The female singer on Adam's team actually got the popular vote, but the Adam vote pushed Lucca forward.
