I give the album a 7 out of 10 just because I like Katy. There's some great songs on it but there's also a lot of basic songs on it. Lirically it's a great album but the sound of it is very dated and nothing new. Katy should leave Dr. Luke if she doesn't want to end up like Ke$ha.
Best songs: Legendary Lovers, Roar, TIHWD, International Smile, Walking on Air and Dark Horse and maybe Birthday
