+3 Shakira
Truly the most versatile, and ironic because I like Beyonce and Rihanna more than her

But really, that write up was brilliant Ragua, and probably persuaded many people. Just by listening to her engilsh-debut
Laundry Service, and her newest album
She Wolf, you can easily see that she has changed. While she may be doing what's the norm at the moment, but she can do it in a way that she can easily be recognized.
+2 Rihanna
While she may not be the most versatile artist, she has def. proved that she can switch up her style. I mean, just listen to her debut
Music Of The Sun, then listen to her current album
Rated R. See a change? Yup. She can sing Carribean, Pop, Electronic, Ballads, Acoustic, Rock, Hip-Hop, R&B, and much more. This should prove how she can be versatile. She might have recently started writing her own music, and started getting more personal, she has remained a powerful force in the music industry along with the remaining ladies.
+1 Beyonce
This took a while for me to put this down. Beyonce is def. one of my favorites, but let's be real here. Her debut was pure Hip-Pop.
B'Day was Pop.
IASF is more of an acoustic/electro pop album, but she isn't the most versatile. Don't get me wrong, her music is amazing in every way possible: vocals, production, and lyrics. But I'd like to see her change it up on the next album, switch it up!
