I think it's funny to have a song like this that staunch conservatives and staunch liberals judge harshly for their own supposedly unrelated reasons.

What the puritans miss in the process is an incessantly fun pop song with enough guitar heft that it could easily be made into a heavy rock song, and the only thing out of place would be those sensual, objectifying lyrics.

Like any peak Katy Perry song, "Teenage Dream" is built on a single chord progression that receives a collection of melody, instrumentation, and dynamics updates to bring "development" to a song that really doesn't develop in terms of music theory. And here too, maybe the musical liberals and conservatives are also aghast.

But that chord progression is voiced so excellently with its guitar, power chords on the pick-up notes over the square, sure beat.
