X Factor Australia” promised to deliver the best of the best episode on its third live performance night, and the magnificent seven certainly rose up to that challenge.

The magnificent seven were tasked to perform a song – from a selection of some of the world’s greatest hits – chosen by the public. Adding pressure to an already tense-filled night, the contestants only found out which song they are actually performing right before they sing. Adding star factor to the hit reality competition, the Hall Famers returned to mentor the finalists, while judges Adam Lambert, Guy Sebastian, Iggy Azalea and Mel B made their teams rehearse two songs.

Guy appeared to be a nit-picking critic during the entire episode, with Mel B even calling him “grumpy pants.” However, his singers stood out from the pack that night, receiving an extra push from “X Factor Australia” 2013 winner and Eurovision Song Contest runner-up Dami Im. Fuelled by Dami’s inspiring words, Chynna got the judges’ approval after performing “Mercy” by Duffy. She got a standing ovation from all three judges except Adam, who still said loved he her swag this week, including the growling at the end. Mel, on the other hand, said she’s beginning to see Chynna’s “X Factor” properly.

Dami also got the chance to talk to Guy’s other singer, Davey Woder. While Dami barely got a word in during their conversation, Davey also appeared to be inspired and gave an impressive rendition of “Working Class Man” by Jimmy Barnes. The judges loved it, and Guy even bravely calls him a new icon.

The rest of the top seven earned mixed reactions from the judges [see list below]. If Monday’s decider was up to the judges, any of these five would go home. However, considering the two back to back shocking elimination episodes, anything could happen.
