John Cooper, frontman of Christian rock band Skillet, has discussed the criticism the band faces from some Christian critics who believe hard rock music is inherently demonic or evil. In a podcast appearance, Cooper explained that he has learned not to attempt convincing certain strict Christian denominations that hard rock is not sinful, instead choosing to remain authentic to himself and his artistic vision. He argues that music is a neutral tool belonging to God, and that intentionality and heart posture matter more than the sound itself.

Skillet has achieved considerable commercial success despite this criticism. Their 2009 hit "Monster" recently became the first Christian rock song to reach one billion streams on Spotify, having now surpassed four billion global streams. The band has sold over 23 million albums and averages 12 million monthly listeners on Spotify. Earlier this year, their European headline tour drew record crowds, including record-breaking ticket sales at Zénith in Paris.
