Here are Simon Cowell's top tips for The X Factor auditions and those wanting to sing for the judges.
Try outs for this year's series are coming to London on SUNDAY at the ExCel centre as the auditions tour for the thirteenth series rolls on.
And if you're thinking about auditioning, Simon Cowell has some tips.
"Song choice is number one," he says. "What you don't want is an obscure album track with an awful melody and terrible lyrics. Choose a song that's going to get you remembered."
Simon continued : "Rehearse, that's what excites me when I'm sitting in that arena, when someone nails a song it's the best feeling in the world.
"Be original, try not to copy what everyone else is doing. You always want something different."
The music mogul also suggested: "Don't be afraid to be what I would say is 'out there', stand out from the crowd."
And Simon concluded: "And if necessary, don't take no for an answer."
