Rihanna gained success through an audition with music producers in 2003. She signed a six album deal with Def Jam Recordings in 2005 after Jay-Z requested an audition. Rihanna does not have a clear ideology in her work but has explored themes of violence, sexuality, and relationships. Her hit song "S.O.S" contributed to her worldwide success and image as a newly rebranded artist after "Pon de Replay". Her video for "Russian Roulette" showed a darker artistic direction and her transformation from girl to woman.
