After winning 'The X Factor' less than 24 hours ago, the four piece - made up of childhood friends Mustafa Rahimtulla, Ashley Fongho, Jamaal Shurland and Myles Stephenson - shot straight to number one with their original winners' charity single 'Dimelo', which features Wyclef Jean and Naughty Boy.
As of writing, the original version of the track - without the rapper and producer featured on it - is at number three below Ed Sheeran and Beyonce's 'Perfect', while their song I'm 'Feeling You' is number four, fifth is 'Mona Lisa' and 'Mamacita' made it to number six.
The boys beat off competition from Grace Davies to be crowned winner of the talent contest, however, the 20-year-old beauty's song 'Too Young' has just made it into the top 10, sat in eighth place.
It comes after the group revealed they have a catalogue of songs they've written and are ready to release.
Fans won't have to wait too long to hear some new music from them as they've revealed they've already got loads of tracks they penned before and during the competition that are ready to drop.
Speaking on 'Lorraine' on Monday (04.12.17), Ashley said: "We have a got a backlog [of songs] but we always want to better ourselves so we write every single day ...
"That's the good thing about 'X Factor' - we have to write songs every week and you write four or five and only one will get used so we've got other stuff we can go back to."
The band's mentor Simon Cowell is convinced they will become as big as One Direction - who finished third in the 2010 series of the show, and have gone on to sell more than 70 million records - and, although they were the early favourites, they never expected to win the show and were just using the competition for "exposure."
Ashley explained: "I think for us, we knew who we wanted to be and we knew who we wanted to be going onto the show and obviously we saw it as a good opportunity to get some exposure for ourselves, we didn't know it was going to go this far. I think we were just fortunate in that when we said we wanted to do our own songs, the staff were kind of like: 'OK, if it's really what you want to do, it's a risk but fine.'"
