I'm a little bummed that they didn't show her blind audition, but I remembered they also did the same thing to Cassadee Pope's battle round. So I'm hoping that the producers did it intentionally in order to showcase her later.
I think they short-changed Cassadee Pope's battle round because they didn't know what they had in her. She didn't take off until she sang Over You. Sort of like how no one thought much about Dia Frampton until she reached the live round.
The montages are still annoying. They won't even show the full performance on their website or YouTube channel. It short-changes the artist, especially when the iTunes version of the song is usually of a lesser quality than their performances on the show (just listen to how screwed up Terry McDermott's studio recording is for Carry On Wayward Son).
