Interesting ideas here. I guess the impact of the parental disapproval factor will be diminishing over time, though not everywhere nor for everyone. The 'we've got our love even though they all disapprove' trope still seems to crop up in pop songs these days.

Regarding underestimated qualities, perhaps Avril Lavigne should write a follow up to Sk8r Boi, in which the rockstar couple have split up, and he meets the ballet-dancing prom queen in later life.

I actually heard there was talk of turning the song into a movie - so there's a ready-made sequel right there.
