It says so. The American singer is in the process of writing and composing darker songs for her next album.
Speaking of the sequel to the One of the boys, Katy Perry previewed how this new material sounds so far ...
"My new music will continue to be fun, but in a darker line ... but not so much that it is considered heavy. You have to keep changing, evolving ... if you do the same thing every time, this is worse than Chinese torture.
Currently there is the GaGa, which is like from another world; Ke $ ha, who is the girl who always goes from party to party; Rihanna, who has transformed the urban world into her own universe ... I am going to compete with them, only mine will not sound the same as what they have been doing".
