Sunday's performances had the surviving contestants perform covers of songs composed by their music idols.
Two Nigerian Idol hopefuls, Faith Mac and Dotun have been eliminated from the Top 11 stage of the competition after scoring the least votes in the first round of public voting.
During the live show on Sunday, the show's host, IK Osakioduwa, revealed the names of the contestants who made it through to the top nine stages of the competition.
To arrive at the top nine, each lucky contestant was given an opportunity to prove their mettle with their song selection.
This week's performances had the surviving contestants perform covers of songs composed by their music idols.
The judges, Seyi Shay, DJ Sose, and Obi Asika, on the other hand, watched in the capacity of audience members as the power to save and eliminate contestants had since left their hands.
Kingdom, who revealed that he idolised 'Teni The Entertainer', handed in a percussion-backed rendition of the hit song "Uyo Meyo", which was well-received by the audience.
DJ Sose said that he seemed very comfortable with the song and Seyi Shay noted that the performance was emotive.
Daniel went with a rendition of James Arthur's "Empty Spaces", which Seyi Shay criticised for lacking verve.
Obi Asika was also critical of the song arrangement, but DJ Sose was of the opinion that he did a good job. Faith Jason, dressed in an all-red attire, performed a cover of Jon Bellion's "All Time Low", the same song he performed at the auditions, and the judges loved it, even more, this time around.
Seyi Shay could not contain her excitement.
Beyonce, who disclosed her admiration for the K-Pop band BTS, chose to perform a cover of the track "Dynamite", with assistance from the live band.
DJ Sose commended her for showing her playful side, while Obi Asika noted her growth through the stages of the competition.
Emmanuel, who had clearly become a fan favourite, rendered a soulful cover of Labrinth's "Beneath Your Beautiful", which was lauded by Obi Asika for the palpable emotion.
Seyi Shay described the performance as "captivating", while DJ Sose added that he would do better as a live performer and not a recording artiste.
The sixth contestant to be saved by the viewers was Akunna, the entertainment lawyer. Dressed in a flowing red gown, she took on the difficult task of covering Beyonce's "XO", but her strong voice carried the performance.
The judges lauded her vocal range, as well as her stage presence.
The voters also appeared to show kindness to Clinton, who put his vocals to the test with John Legend's "Tonight", with some help from the live band.
Seyi Shay felt that the delivery was not "natural", but praised him for his vocals. On his part, DJ Sose felt that he "owned" the song.
There was a fleeting moment where IK Osakioduwa goaded the judges to disclose which of the remaining contestants would be saved if it was up to them. Both Obi Asika and DJ Sose went with Francis and Comfort, but Seyi Shay decided to plead the fifth.
Also getting saved by the voting public was Francis, who chose to perform Sam Smith's "Writing On The Wall", the theme song for the James Bond film Spectre. It is always difficult to match the energy of a Sam Smith song, but Francis pulled it off brilliantly, much to the applause of the judges: Obi Asika described his voice as a "lethal weapon."
The ninth and final contestant to earn nods from the viewers on the night was Comfort, who found it difficult to control her emotions on learning that she had made it to the next stage. This meant that for Dotun and Faith Mac, their respective journeys at Nigerian Idol Season 6 had come to an end.
For her performance, Comfort went with a cover of Adekunle Gold's "Ire." The first few seconds were fraught with nerves, but she recovered quickly to deliver a strong performance, which Seyi Shay praised for the confidence displayed.
