Olly Murs has said he's not recognised enough for his achievements.
Since leaving The X Factor as runner-up in 2009, Olly has released three albums and sold almost three million copies.
He said: "People come from The X Factor and they might stick around for a year or two, so I'm proud to carry on selling records, to grow a fanbase and be on three albums.
"It's a massive achievement and it doesn't get highlighted enough, the three albums I've released and the sales I've achieved. I think it's amazing and I'm really chuffed, but it doesn't get written about."
Asked whether it bothered him, the singer said: "Of course it does... From an industry point of view, press too, there is snobbery that I'm from The X Factor, that I didn't come through the right channels, and they're not into it.
"I don't understand it. It's clear in writing how successful I've been and what I've achieved."
Olly said it was "unlikely" he'd be doing the next series of The Xtra Factor.
He added: "There's been a lot of speculation, but I've never said it was definite that I wasn't going back, just that it was unlikely due to my music career. I might still do it, we'll see. I've enjoyed The Xtra Factor, it's been a great part of my career."
