Song: "When You Believe"
Thoughts: Siobhan definitely showed off her vocal ability, but I still thought it was pretty yawn-worthy. And for real: why the butterflies? Randy judged it as just OK for him, though Ellen disagreed, saying it was confirmation for her being there. Kara admitted she still didn't know who Siobhan was, and Simon referred to the arrangement as old-fashioned.
Is Siobhan still an idol?
