KSI thinks some people "despise" his success in the music business.
The YouTuber-turned-rapper – who released his debut album, ‘Dissimulation’, in May – believes many people remain dismissive of his musical talents.
He said: "When the general public sees a YouTuber wanting to do music, it just leaves a weird, sour taste in their mouths. People just despise it."
But now, the 26-year-old star thinks fans who listen to his music are appreciative of his talent.
He told NME magazine: "I feel like a lot of people who wouldn’t normally watch me have listened to the album and gone, ‘Oh wow, there are actually songs that I would put in my playlist.’"
Despite this, KSI is genuinely surprised by his chart success, saying it proves "how powerful the YouTube fanbase is".
He reflected: "I didn’t actually realise I’d be able to compete for Number One.
"To even be in the Top Five would be incredible. Not that many people do that … I never thought I’d be able to be anywhere near it."
Meanwhile, KSI previously admitted to disappointing his parents when he shunned university to become a YouTuber.
The internet star was sent to a private school in the hope he would eventually become a lawyer or doctor – but he ultimately decided to pursue a different path in life.
He said: "Eventually I decided, ‘You know what, screw it. I’m going to make them proud through the whole YouTube.’
"As long as I can get rid of all their debts and make their lives comfortable, that’s all that matters."
