So, I was sort of apprehensive about her having a disc for her alter ego Sasha Fierce but it blew me away. The first Disc, I am, is the softer, sweeter more emotional side of Beyonce's music with haunting ballads and soothing love songs like Satellite, Halo, If I were a Boy where as Disc 2, Sasha Fierce had the up tempo tracks like Diva, Radio, Single Ladies. 

To be completely honest, this is the first album in a long time (a double disc album nevertheless) where I loved every track. There was great continunity even though it was two very different sounding discs and the vocal arrangement and the production was equal to the skill she has as a singer.

Definitely worth the listen. 

when did she get a porn name?

She's been eluding to her stage persona "sasha" for a couple years now, where the fierce comes from .... i dunno.
