Shania Twain is a country singer who was raised out of poverty and is now the best-selling female artist in world history. Her music is country with a popish sound to it. She not only sings music, but writes her own music along with the help of her husband Mutt Lang (A.K.A. The producer of many famous rock groups such as AC/DC).
I heard Shania Twain's song, "Man! I Feel Like a Woman!" on a country music station. It's not your average country music, but yet it's not pop.
