I'm not 100% convinced on Saara's song picks, even though everyone seems to love them. I did love her audition, but I always think it's kinda lazy and underwhelming when a contestant repeats a song they've performed before in the competition. She would have to completely change it around or make something new and different with it to really leave an impression.
Also, "All I Want for Christmas Is You" is a dangerous song, which could be an amazing performance, both vocally and entertaining wise, as it could be a disastrous performance.
This could either be what might set Saara to match Matt in the finale or what mean her end in the competition.
Besides that, Matt's songs are pretty much spot-on, I'm quite excited for his "Say You Love Me" performance since I love that song and I actually think he can pull it off.
Also, I'm actually excited for Emily's Mad World which I think might give her a moment, just like what she had with "Creep".
5AM songs are pretty much the same as always, so I don't expect anything different or amazing from them.
