The tune, "Into the Unknown," has an accompanying music video that sees the Panic! at the Disco frontman "giving the performance of a lifetime."
"This is make or break, this is your chance now," he explained in a short behind-the-scenes clip. "Whether or not there is an audience, I’m going to give it all."
The crooner also revealed who his favorite Frozen 2 character is--the goofy but lovable snowman Olaf. "Being carefree, happy-go-lucky all the time. I try to do the same," he revealed.
