I agree with آپ on Firework! I mean, it's not that great!
For me, pretty much every song Katy Perry sings is overated. But Teenage Dream I think is the most overated of all her songs. It's cheesy, poorly written, & she uses WAY too much auto-tune in it. It just sucks in any way آپ look at it, in my opinion. & I don't like the way she makes "love" look in that song. There is no fucking fairytale. There is no flawless romance. It's all phony & cheesy. Real love actually has complications that, if the two people really love eachother, can overcome.
