“‘Hallelujah’ felt much different than most of the other Christmas songs we hear every year during the holiday season,” Seattle’s charlieonnafriday tells Apple Music. “The song pulls on people’s emotions and triggers sentimental feelings, and I feel like that’s what I’ve been doing with some of my new music. ‘Hallelujah’ is also a very celebratory anthem, and I feel like I tend to create songs that render feelings of celebration.”
