I used to think Lady Gaga was just a hack. She was dressing like Elton John, and being intentionally scandalous like Madonna, to compensate for her lack of talent.
Then I saw her do "Paparazzi" acoustically on a piano (ok, might have been a keyboard, but she had no production magic or AutoTune behind her). Other than pronouncing it "Puhpuhrazzi", I was floored. So, I know she has talent.
And she's becoming a guilty pleasure. Her music reminds me more of Ace Of Base than Madge. In fact, "Alejandro" reminds me of AoB's "Don't Turn Around." And that's a good thing. Can't stand Madonna, but I love Ace Of Base (weird, right?).
Sexy? Hard to tell. With her wigs and dress and elaborate makeup jobs, I can't really tell WHAT she looks like, but I think her facial structure and eyes are similar to Cher's, which is only so-so in terms of hotness for me.
But yeah, she's a force to be reckoned with, and that's cool, cuz she's not all bad. And she's a HELL of a lot better than Ke$ha.
