"The X Factor" UK will be airing its live show in just a couple of hours and fans are already betting on their favorite contestants this season. 4th Impact (formerly known as 4th Power) remains as one of the fans' favorites this season, but it looks like their song choice for their upcoming performance is already making several people worried. Did they make the right decision or will this totally change their standing on the show?

4th Impact remains as a top favorite in "The X Factor" 2015 among fans and viewers. The all-girl group from the Philippines can easily blow away anyone with their powerful vocals and energetic performances on stage, but it looks like several fans and personalities are already expressing their concerns over the group's song choice for their upcoming performance.

4th Impact will be performing "Sound of the Underground" in the show's upcoming live show, Unreality TV reported. This has raised concerns among fans and viewers alike, as the show was performed by no other than "The X Factor" UK 2015 judge, Cheryl Fernandez Versini.

The outlet noted that former "X Factor" winner Sam Bailey expressed her concerns over 4th Impact's choice of song.

"...that might be a bit weird for Cheryl to listen to one of her own songs. I'm not really sure how you can change up that song. I don't know what they are going to do with it," she said.

Meanwhile, it seems like the girls remain confident of their upcoming performance, as another report from Unreality TV revealed that 4th Impact is very much excited for tonight's live show.

Almira, a member of 4th Impact, shared a photo of herself preparing for the live show and wrote: "Let the day begin." The girls also shared with everyone on Twitter that they are excited to see what will happen in tonight's episode.
