Really people. Stop Comparing Good Artists. You can compare the sh*te gay wankers like Chris Brown. But serously Katy Perry's E.T is good - with Kanye... not so much. Ri-Ri's S&M is ace. I Like It Like It. If she gets - when she gets #1, it will be her tenth in the US and most likely California King Bed will reach number one also. But Seriously, I Have both albums - Loud & Teenage Dream - & Ri-Ri's other 4 albums and all of her featuring singles and songs. And i have Katy's I Kissed A Girl & Hot N Cold & is hoping to get One of the Boys [album] for my birthday. Before anyone says i do like Gaga, Beyoncé, Shakira, blah blah blah. But my fav artists are Rihanna, Jessie J [yes i am from the UK] & Katy Perry with Avril Lavigne coming in behind them. My Point is... WE ALL HAVE DIFFERENT TASTES IN MUSIC AND WE SHOULD RESPECT THEM (unless you like Chris Brown or Justin Bieber - then we can slag you off) :)
