He said: “Look at Mariah Carey. She has a little break. People look at it like it’s over. They have to throw dirt on her.
“Then all of a sudden, she’s the biggest thing to hit the stage again. Even bigger.
“You see what I’m saying, and I think that happens. So when you look at it like that, you’ve got to apply yourself.”
The 36-year-old star even wants to use the negative comments of his critics to further fuel his desire to achieve chart success again.
He added: “I feel like, if people want to count me out – which I don’t know how you would count a guy out with 30 million records sold – then OK, I’m going to use it to my advantage.
“And I just felt that, since you don’t want to acknowledge me, or if you want to act like I don’t exist then good, don’t check for me. But you will eventually hear from me – and it works better that way.”
