Elaine or Rapunzel?

Aside from the fact that this is just a peppy song in general, I couldn't help but compare Rapunzel to the Lady of Shalott from the poem. Like Rapunzel, our Lady starts out pretty positive about her experience, but then you start to see how isolated, lonely, and bored she is. Plus, they're both shut up in towers singing their hearts out, which obviously makes them the same person.
