As It Was by Harry Styles has always bugged me - it's a-Ha type synths hide a very dark track, and it feels like it's really double the speed it should be. Also it seems quite indie and alternative with mention of pills and isolation.
So I paired it with the half-speed indie anthem Bitter Sweet Symphony by the Verve and turned it into a lighter waving anthem. As you do.
