I don't know if it would mean anything, but I can list off the names of the songs played in each video... but.... um. 1 and 3 use the instrumental of step on your heart (except Tianyi sings the intro piece of the song at the end). 2 features FEEL YOUR DREAM. 4 uses nothing. 5 cuts off the first intro of step on your heart, but she sings the rest.

See, now I'm not sure if it's even useful at all lol Basically every video uses step on your heart except episodes 2 and 4
