Coldplay have said their rigorous recording process makes X Factor “seem like a walk in the park”.
In an interview with The Sun, singer Chris Martin said the band had given up recording one album before starting work on what eventually became their new effort 'Mylo Xyloto'.
"Each song goes through such a harsh selection process just to get recorded,” he said.
"It makes The X Factor seem like a walk in the park. We scrapped a full album before this. But we always do that."
Drummer Will Champion said: "We'd started an acoustic album but then we wrote 'Paradise' and knew the acoustic thing didn't have legs."
Coldplay's new album, which is the follow-up to 2008's 'Viva La Vida and Death And All His Friends', is released on October 24.
