The musician, who has daughters Violet, six, and Harper with wife Jordyn, said he would be really furious if one of his kids was cut down by a panelist on a show like 'The X Factor' or 'American Idol', reported Femalefirst.
"That is what irritates me out about these shows where people are judged so harshly by established musicians that hardly even play and instrument on their own albums. It makes me really mad," said Grohl.
"I swear to God, if my daughter walked up onstage and sang her heart out and some billionaire looked at her and said, 'No, I am sorry, you are no good' I would throttle that person, I swear to God. Who are you to say what is good or bad," he added.
