After Hollywood Week's Genre Challenge and Duet Challenge, judges Lionel Richie, Luke Bryan, and Katy Perry have narrowed down Idol's season 19 crop of contestants to 64. To make the next round — the Top 24 — everyone gets one last chance to plead their case by way of a show-stopping performance for the judges in the, yep you guessed it, Showstopper Round. But moving from 64 down to 24 is a huge cut, so be prepared for some of your favorites to be stopped short of making it to the audience vote next week. The music business is tough, people!
