The music scene, from the female artists, is currently the strongest it has ever been. Lady Gaga, Katy Perry, Rihanna, Beyonce, Kelly Roland, Nicole Scherzinger, Kesha, Shakira, Stacey Ferguson, The Saturdays, Jenifer Lopez etc etc etc.
Given this gold mine of talent and material, this really could of been one of the greatest ever compilation albums. Yes, there are a small number of classic tracks from the above, but this is padded out by a lot of tracks from 'B' listers, and in a lot of cases it is not even their best offerings.
I am afraid to say this will be best remembered by what is not on it, rather than what is.
