SONG REVIEW: Katy Perry- "Teenage Dream."

I said I would do a review on this song about a week ago.
Well, at first, I absolutely HATED the song.
After a few days of thought and a few more listens, I have kind of changed my mind.
But only kind of.
The second single from her sophomore album, also titled Teenage Dream, was released to radio last week, and debuted at #20 on the Billboard Hot 100.

So, yeah, it's definitely not as good as "California Gurls," but it's not terrible either.
My grade?

... B-
