Lady Gaga and Michael Jackson have VERY DIFFERENT STYLES. Michael Jackson was idolized as Michael Jackson the person. Lady Gaga (do we even know her real name?) is not so much a person as she is an idea. She stands for something. She thinks of Yoko Ono as an influence. If anything, she has more in common with Marilyn Manson than Michael Jackson.
There's a video on youtube addressed to Obama where she says "I hope I don't have to do a protest song". That's more NT for ya. an SFP would be doing "heal the world"
