I will admit that Lady Gaga is an amazing musician. I've loved her since "Poker Face" and since then, she has been #2 in my musical life. But she is no where near Rihanna. Rihanna has been out since 2005 and has released 4 albums and has had countless Top 10/ #1 singles. Lady Gaga does have a strong voice, but Rihanna can SANG! You may not think she can sing, but if you watch Rihanna "PERFORM" like she is supposed to and actually sit and get into a song, you will see that she is an amazing vocalist
