the movie uses mostly music that's dated now

When he showed the daughter going through a Gaga phase it was to show how kids have those fleeting but intense fascinations of stars like that, and then he showed her as a woman who was beginning to come of age when she had left that silly phase behind at the end of the movie.
If a ~rebellious unattractive girl with dyed hair in her embarrassingly defiant teen years being presented as the typical gags stan(and when having outgrown this phase to become a normal person, is no longer a gags stan) is a good thing, then slay I guess?
