'American Idol' season 16, episode 11 recap and performances
American Idol/YouTube

"American Idol" returned on Sunday with the second half of its Top 24. The 12 artists who didn't perform last week took the stage this week, starting with solo performances to prove they deserve to stay in "American Idol" season 16. But who will judges Katy Perry, Lionel Richie and Luke Bryan send on to the Top 14, and which five singers from this group will end up going home? Here are the highlights music fans need to see from Sunday's show:

1) Mara Justine's dazzling cover

If you're going to cover Whitney Houston, you had better come correct. That's exactly what Mara Justine did with her version of "Run To You." She delivered every ounce of earnestness and power that the classic ballad demanded. Of course she wasn't going to reach the heights of the original, but for her age and where she is in her career, this was stunning. Watch it for yourself by playing the video above. With this performance, Mara should not only have made the Top 14, but established herself as a serious pick to make it to this season's finals.

2) Amelia Hammer Harris' odd song choice

Amelia Hammer Harris may have just ended her "American Idol" career with a very confusing song choice Sunday. She opted to cover "Believer" by Imagine Dragons, which is not really the kind of song you'd expect on "American Idol," because it involves a fair bit of screaming and there's not a lot of places where someone could show off their vocal ability. Not only that, but it was a poor fit for Amelia's voice and strengths, as she seemed to be reaching through most of the performance. The result was a disappointing cover that leaves Amelia behind the proverbial eight-ball going into Monday's celebrity duet episode. Unless she has one of the best performances there, she'll likely be going home.

3) Marcio Donaldson channels Natalie Cole

It's always a good thing when an artist covers a song that's different from the usual two dozen songs we seem to hear in singing competitions, and that's what Marcio Donaldson did Sunday when he chose to cover "Inseparable" by Natalie Cole. It was a risk taking on a song by a female artist, but Donaldson pulled it off with a sincerity that the late Ms. Cole would have been proud of. Is it the most popular song he could've covered? No, but America isn't voting yet. The judges are, and hopefully they will advance him to the next round.
