The contestants continue, this season, to both surprise and impress with their song choices, and especially with their individual interpretations of those songs. From last week, one case in point whose originality lingers as a sterling example: Taylor Alexander, doing a very country, very male version of Cher’s “Believe.” It was good enough, and unusual enough, to land him on Adam Levine’s team. This is the final week of the audition round, and last night, once again, provided lots of entertainment, talent, and, yes, emotional moments.
