Rak-Su have revealed what exactly their band name means.
The four piece, mentored by Simon Cowell, are the current favourites to win.
Rak-Su are made up of four pals but what does their name actually mean?
Well they've now explained on their website that it comes from the saying "Tracks vs Suits" which means 'Music & fun vs Adult Life'.
Rak-Su will be back singing tonight on ITV as they compete to make the next weekend of live shows.
This week FOUR acts will leave this weekend as the finalists sing over Saturday and Sunday night once again in their categories.
This time around the Boys and Groups are first up on Saturday while the Girls and Overs will sing on the Sunday evening with this week's Crazy In Love theme.
Once again, Rak-Su will be singing a brand new original song.
After the performances, at the end of each live show a public vote will decide which two acts are immediately given the boot with the bottom two sing-off axed.
Instead, the acts who top Saturday and Sunday's vote face off in a new 'prize fight' to win a special reward.
The X Factor 2017 continues this Saturday at 8:10PM and Sunday night at 7:30PM on ITV.
