- Contractual Purity: She had to warn her younger fans not to watch Secret Diary. However, the poster appeared on ad boards across the land...
- Ear Worm: "Why you gotta play that song so loud? Because we want to! Because we want to!"
- Hilarious in Hindsight: Go back and watch her video for "Because We Want To." See if you can watch the beginning (when she gets beamed down from a giant spaceship) and not make a Doctor Who reference. There's even a very Judoon-like anthropomorphic rhino in the video.

However, since she's had more success as an actress than as a singer, Mandy Moore might be a better comparison.
