Hach ha that famous second album. Always interesting again. Will it be as good as the first album? What can I expect? First one thing: It is definitely more commercial. More Beats & Drums, etc. Also this album was because not spared. A look at the list producer can explain everything: Dr. Luke, Tricky Stewart and Max Martin. The creme de la creme of the producers who have already made Britney Spears, Rihanna, Kelly Clarkson, Kylie Minogue or Christina Aguilera famous. I find personally super. The level increases as immensely. All songs are extremely successful. The first album was more pop rock. This is definitely a pop album with attached interpretative rock elements. She now has a song with Snoop Dogg, well if this had to be now, was once an open question. But has certainly increased the sales figures. I highly recommend this album to anyone who I was not disappointed and unfortunately that happens very often in the second films of various artists. Not with Katy Perry! Buy!
