This week on The Voice, it’s the Playoffs: Four hours in which the remaining team members for each judge compete to survive, and move on to next week’s live shows. Jennifer Hudson and Blake Shelton cut their teams in half on Monday’s two-hour edition, and Adam Levine did the same last night. That means tonight belongs to Miley Cyrus, whose six singers, by the end of her hour, will be bisected to three. And the level of talent, all this week, has been competitively, and creatively, impressive.
