The singer said that he feels "re-energised" after taking a break from his solo career and wants his new LP Take The Crown to be "massive".
He said: "After the Take That reunion - a busman's holiday, a break from my career which re-energised me in many, many ways - I wanted to come back with a massive solo album.
"My main priority was to write what I consider, and hopefully what the world would consider, to be hits. I'm very excited."
Williams releases his ninth solo record - which was produced by Jacknife Lee (Two Door Cinema Club, Snow Patrol) - on November 5.
The LP will be preceded by the single 'Candy' on October 29. The star describes the track as "a summer song", adding: "[It's] about a girl who thinks she's great. And she might be, but she's a bit nefarious with her ways.
"Some songs take an age to write and some songs just fall out of your mouth completely formed, and you don't have to think about it. I don't know why that fell out of my mouth and out of my brain at that particular time - it just did."
Williams recently released the tracklisting for the album, which will be put out in both standard and deluxe editions.
