As for sound..
2005-2008,
USHER= R and B
AKON= R and B
Aguilera = SOUL / R and B
Rihanna = Pop/ R and B
Ne-Oh= R and B
Katy perry = Pop rock
Enrique Iglesia= Latin/Pop
In the U.S dance music was never allowed to be played on radio, which is ONE REASON why madonna's last album never really managed to go full fledged diamond in the U.S or onto the mainstream pop radio..
Guess who changed that?
Lady GaGa- Late 2008 Electro/techno pop
the only one to do it in the U.S too.. everyone on the list above was a step behind her, and that literally pushed her up dramaticaly in fame.. atleast that's what I saw it to be.. and her style was way ahead of its time..
Now?
Usher = Dance/electro pop
Rihanna = Pop/R and B/electro pop
Katy perry = Dance/electro Pop
Enrique= Dance/Electro Pop
Ne-Oh= Dance/electro pop
Akon = Dance/electro pop
Aguilera = pop/dance/electro pop
Don't tell me she hasn't done shit for the music industry, because that just shows how misinformed you are about the pop music industry.
