The new seasons of American Idol and of this show both have started off with an impressive array of talent. On this show, though, the most fun of all is to be had right now, as the blind auditions continue – and when the judges, after spinning around in their chairs to show support for the formerly unseen singers, have to compete with one another to persuade those singers to join their team. This year, Pharrell is cleaning up, Adam Levine is striking out, Blake Shelton is loving Levine’s rising frustration level – and Christina Aguilera already has prompted one tender TV moment, when she urged Pharrell to join one unclaimed young contestant in a duet of one of his songs, “Happy,” after she remarked, post-rejection, that she sang his song in her high-school a cappella group.
