Wayne Coyne is the Lead singer for the band The Flaming Lips. If you listen to a few lyrics, from their song you can hear it. For example Do You Realize and Vein of Stars sound very freethinking.
Coyne is a comically rationalist atheist "I wish I did believe in God. It would be a great relief to think, 'God'll take care of it. God'll put gas in the car tomorrow" who makes music that, for all its quirkiness and frivolity, is in its essence spiritually transcendental. [...] For an atheist, he has a touching faith in the power of song to ease our shared burden. "There's some comfort in saying, I'm joining this long line of humanity," he says. "We're all going to get in line and our parents will die and our friends will die but I'm in the line with you and you're in it with me and, for some reason, if we're in it together, it's better than doing it alone. That's why music is always going to save us."
