The Believe star was speaking at a gathering in London hosted by The Voice UK presenter Reggie Yates.
The Mirror reports that, when Yates tried to offer Bieber a seat at the beginning of the conference, the young singer barked: "No, I want to introduce my song."
The Canadian star was then said to be visibly irritated by the sound system, and cut the track 'All Around The World' mid-play, saying: "It sounds so bad!"
He is also reported to have scowled when he was compared to Justin Timberlake, stating: "I sound nothing like [him]."
Discussing the recording of a song, he said: "I was in some random country," before being told it was Indonesia.
"I recorded it in a studio," he continued. "Some little place. They didn't know what they were doing."
Bieber also corrected London interviewer Yates's pronunciation, commenting: "It's 'think' with a 'th', not an 'f'."
