I know the song and the dance, but I don’t know the group or song name. Please, I’ve hade this song stuck in my head for two years. In all the moves they’re kicking the feet that’s off the ground. The song goes like “where you been all my life, yeah, yeah, yeah, yeah” or something, I’m not that good at English. It’s an upbeat song and it’s a bg. Probably 4th gen.
