I don't know why, but every time I listen to Katy Perry's 'Teenage Dream - The CompleteConfection' album I become sad.

The One That Got Away (Acoustic)
Who Am I Living For?
Pearl
Hummingbird Heartbeat
Not Like The Movies
Wide Awake

They are all so sad and moving songs. I can't help but be sad when I listen to them.
Maybe I'm a masochist because I enjoy these songs so much despite they make me sad.

P.s.: It was a bad idea to read a ChaeRa fanfic while I was listening to these songs. CL cheated on Dara and CL felt miserable... *cries* WHY CHAERINNIE, WHY? T____T
