Last night there was a massive fireworks display and I was watching it at this park, and this kid began singing the chorus to "Firework"

Katy her impact is unbelievable, "baby you're a firework" is ingrained into the mind of every 10 year old
And today during Pride I was waiting in line for the bathroom and I heard these two middle aged women discussing Miley's new video, one of them referring to the twerk bit as "she did the bum shaking dance"

Miley her social relevance and multi-generational appeal.
