Rihanna relies more on her sex appeal and what her team wants her to look like. It's always felt very fake from Umbrella on. Lady Gaga's really not my cup of tea but you get the sense that a lot of the direction in her career comes from her. Even if she's not totally original herself.
Gaga couldn't be the first to do any of the things she's done simply because Madonna & Cher carved the path for her. I'm just annoyed that what set Gaga apart from them is now being replicated by far too many other Pop singers right now. It's "hip" to be odd now all because Gaga blew up.
It may be true but the girl just won't go away. The funny thing is she's more popular outside of the U.S. even though it's the biggest music market. She hasn't had a album debut at number one in six tries.
