The semi-final results of "American Idol 2016" season 15 was not without elements of disappointment. A total of five contestants were sent home on Thursday, even though some of them gave convincing performances in both the solo and duet rounds.

People will have their own opinions about the 12 contestants who performed in the semi-finals 2, but if one is to pick the biggest disappointment of this episode, it is the elimination of Shelbie Z. Her performance of Gretchen Wilson's "Work Hard, Play Harder" on Wednesday was good, and it was followed by a beautiful rendition of "Bohemian Rhapsody" with Constantine Maroulis on Thursday. But judges Jennifer Lopez, Keith Urban and Harry Connick Jr. sent her home.

Here is the list of songs performed by the remaining 12 contestants with former American Idol contestants during the elimination night:

Amelia Eisenhauer: "Suds in the Bucket" with Kellie Pickler

Kory Wheeler: "Bennie and the Jets" with Haley Reinhart

Lee Jean: "Home" with Chris Daughtry

CJ Johnson: "The World I Know" with David Cook

Manny Torres: "No Air" with Jordin Sparks

Jenn Blosil: "My Funny Valentine" with Constantine Maroulis

Tristan McIntosh: "Best Days of Your Life" with Kellie Pickler

Olivia Rox: "Light On" with David Cook

Adam Lasher: "Can't Help Falling in Love" with Haley Reinhart

Dalton Rapattoni: "Higher Ground" with Chris Daughtry

Trent Harmon: "To Love Somebody" with Jordin Sparks

Shelbie Z: "Bohemian Rhapsody" with Constantine Maroulis

Shelbie Z's performance of "Bohemian Rhapsody" with Constantine Maroulis was perhaps the best of the night. Her performance in the solo round too was good, but she was unceremoniously sent home. Other singers like Kory Wheeler, Trent Harmon, Dalton Rapattoni and Olivia Rox put up a good show. Performances by the rest of the contestants were also decent.

At the end of the day, the judges had to choose only seven from the lot and send five singers home. It was not an easy job, but they had to. And they eliminated Adam Lasher, Shelbie Z, Kory Wheeler, Amelia Eisenhauer and CJ Johnson on Thursday. Now, the number of contestants has been trimmed to just 14 after the semi-finals.

Here is the list of top 14 contestants:
