Lady Gaga's has a very nice scent. Justin Bieber's perfume is also surprisingly good. It even won some awards which is uncommon for a celebrity perfume. Rihanna's is way too sweet! lol it's like cotton candy in a bottle =P
There is no "original" artist. The influence of the artist is always seen in his or her work. Madonna was inspired by many people e.g. Marylin, Greta Garbo, Marlene Dietrich. There is nothing new under the sun. The trick is making it your own and adding on your own legacy. Sure on the surface Madonna took the platinum blonde look of Marilyn but she was certainly was not trying to be Marilyn. They have completely different personas and objectives. It's the same with Gaga and Madonna.
You can't be nominated if you didn't do anything...Gaga had Marry The Night which wasn't a big hit *even though at first it was my favorite song on the album...but I'm not bitter* It's really not a big deal you can't be nominated every year!
