Beyonce, Xtina, Pink, Avril and Adele.
Lady Gaga is an attraction. She tries so hard to prove people she is an artist, but unfortunately her presence is just a tone of gimmicks. She may be a good performer/vocalist though.
I don't consider the music Katy Perry is pulling as an art. Sorry. Her music is commercialized product for people hungry for generic music.
Britney doesn't even care. She will do or is forced to do what her team says.
