He led the field with six nominations, but David Bowie failed to win any of this year's Q Awards.
The musician, who staged a comeback with the number one album The Next Day, was beaten by Ellie Goulding to the Best Solo Act gong.
His song "Where Are We Now?" lost the Best Track award to "Do I Wanna Know?" by Arctic Monkeys.
Among the winners at the magazine's annual awards bash were Jake Bugg (Best New Act), Chrissie Hynde (Classic Songwriter) and Vampire Weekend (Best Act in the World Today).
Biffy Clyro's Opposites nabbed Best Album at the ceremony, while Suede and Pet Shop Boys were handed Q Icon and Outstanding Contribution to Music awards respectively.
Robbie Williams claimed his Q Idol award was simply invented to ensure his attendance at the bash.
"Of all the made-up awards to get a celebrity to an awards show," he said.
However, he added that he was, "genuinely chuffed. I'm 40 next year and I've been around for loads and loads of years, and people still deem me important enough to roll me out and get me here and give me an award, and for that I'm very, very grateful."
Matt Mason, the magazine's senior editor, said: "It's been a privilege to celebrate another brilliant year for music. We keep being told that these are tough times for the industry, but the evidence here suggests the opposite."
The awards are voted for by Q readers and staff.
