She was never on my radar every ten seconds, I've never followed her calling. I wouldn't know if she has more exposure now or less exposure now than she did before. ~
Gaga has not fizzled out. She's progressing and maturing. The newness has worn off so she is not in the limelight as much, but she is better than ever.
I feel like the hip-hop world has gained a couple of newbies lately that are weirdos~ and seeming to make a name for themselves that way. I don't know about pop stars though! I can't really think of anyone that matches/could match Lady Gaga's eccentricity.
