People develop and change. That was her music then and this is it now -shrugs- The above link just reminds me of Avril lavigne and doesn't sound original, least her music now is original...alteast the presentation and videos are anyway.
Eitherway, she has become Lady gaga otherwise she wouldn't be as a famous or successful as she is now. The market is saturated with, "Angelic singers..." and they don't become super special as after talking about her excellent singing voice, what is there left to discuss/promote?
Same with folk like christina aguleria and britney spears, "the American girl..." that concept has been done to death, so Lady gaga entering that market would be pointless.
What she has done is created something that the gays friggan love, girls friggan love and what everyone else who may not wish to admit it, is catchy. Her music is quirky and her videos get peeps talking.
Smart gurl that lady gaga is.
