Ke$ha. She has had no effect on Pop Culture whatsoever. She will be/is remembered as the drunk girl in the bathtub using Whiskey as toothpaste. Katy and Rihanna actually do give some good pop records. Britney did a lot for pop culture and changed a lot in the game. Beyonce..... she has too many amazing things about her to list (voice, dancing, sex appeal, acting, etc.) Lady Gaga has the voice to back up the performances she gives. She could easily sit down on a chair and sing her songs but instead gives it everything she has to make an amazing performance. Nicki Minaj... she gave me RR so its all good.
