It's pretty amazing how much female pop is coming out all at once. Avril, Katy, MIA, Gaga, Miley, and Sky with Britney coming up in a couple weeks. Too bad Rihanna is taking a break from her album-a-year routine.
Thus far I'd have to say I would rank them: Sky>Katy>MIA>Miley>Gaga
The Katy Perry is just straight up pure manufactured pop goodness but Sky (which I didn't like at first) has this weirdo tech-sleaze vibe to it, and no I don't really know what that means. MIA and Gaga just aren't doing anything for me, and I need to give Bangerz another spin but I remember not being too into it beyond the singles.
