In previous X Factor series' the groups have normally been left to suffer the consequences of the public vote early on, but the array of talent on display this year may mean the category will come out fighting during the live shows.
The first group to impress judges Simon Cowell, Cheryl Fernandez-Versini, Mel B and Louis Walsh were four piece Only The Young.
Mikey, 19, Betsy, 18, Parisa, 20, and Charlie, 17, performed Elton John's Something About The Way You Look Tonight and earned high praise from the panel.
Cheryl told them: "That's how you do an audition. It's so refreshing to actually have somebody come in that's original.
"You are really, really good and really talented," said Mel, while Simon added: "I'd love to work with you."
Next up was boyband Concept, who continued to raise the bar for the groups category with their performance of Labrinth's Earthquake, which Cheryl felt was "something genuine" and Mel professing she would love to see them perform again.
Girl group Arize took on Little Mix's Little Me, while five piece Overload sang Bastille's Pompeii, leaving the judges impressed and, just like the groups before them, earned a place in the arena auditions.
It wasn't all plain sailing for the next group Kitten And The Hip, which comprised of real-life couple Scarlett, 28, and 53 year-old Ashley.
Their performance of Shut Up and Dance failed to win over the judges, all of whom felt Scarlett would fare better in the competition as a solo artist.
"I'm not convinced you work together if I'm completly honest," said Cheryl.
She told Scarlett: "I think that you are absolutely stunning, you've got something. There would be a lot of changes I'd make..."
Mel B added: "I think the man should step back and go, "OK, I'm pushing 60, let my wife be the front of this and just stand down like a man."
Louis agreed, telling the couple: "It doesn't work for me at all," with Simon adding: "It's quite awkward because you are in relationship..."
Asked if she would consider going further in the competition by herself, Scarlett quickly answered: "I would do anything it takes to get there. It is the absolute world for me, I am so hungry for this."
The final audition of the show was an emotional moment for both hopeful Linzi Martin and the judges as the former pop star turned full time mum give one last chance at the music business.
Linzi was once a member of the group Girl Thing and worked with Simon in the early 00s.
But when the group's second single failed to impress the UK charts, Girl Thing were dropped by their music label, meaning their dreams of stardom were over.
Unfortunately nerves got the better of Linzi during her audition for the judges as she gave a vocally shaky performance of I'll Be There.
Louis told her: "I think you're really brave, it must be so tough to come out and do this. I like you, I wasn't crazy about the audition. I think the song was too big for you.
"But I know today means a lot to you. I'm going to go with my heart and say yes."
Mel B also agreed to give Linzi a chance, adding: "You know what? We all deserve second, third, fourth, fifth chances. I'm going to say yes. I would not normally say yes because that was not a good audition, but I felt compelled to say yes to you today."
But while Cheryl was supportive of Linzi's decision to give her dream one last chance, she felt her audition just wasn't good enough.
"It's hard because I completely feel for you and understand you," she said. "I feel I have been so fortunate to have had the journey I had, because I could have been in your shoes. But the audition just wasn't strong.
"I felt it would be unfair to put you through."
Simon agreed with Cheryl, telling Linzi: "Your voice just isn't good enough sweetheart, and I don't want to give you false hope. I know you had a hard time a few years ago and I don't want to put your through this again.
"I can't lie to you Linzi. This isn't for you. Your voice just isn't good enough babe and I'm going to have to say no. I'm really sorry."
The X Factor returns to UTV next Saturday at 8pm.
