Her music has changed many times. Its usually subtle and depends on who she works with, which is the same with other artists Britney/Madonna etc so I don't really get that "drag". She's been stuck in a rut since 2008 though.
Her image has changed dramatically since her debut though (even it's been stagnant in recent years.) Like night and day, even down to the way she holds her body/mannerisms.
Me. I Am Mariah... the Elusive ChanteuseMe. I Am Mariah... the Elusive ChanteuseMe. I Am Mariah... the Elusive ChanteuseMe. I Am Mariah... the Elusive ChanteuseMe. I Am Mariah... the Elusive ChanteuseMe. I Am Mariah... the Elusive ChanteuseMe. I Am Mariah... the Elusive ChanteuseMe. I Am Mariah... the Elusive Chanteuse
This will go down in history as one of the best album titles EVER.
You light me up inside
Like the 4th of July
Whenever you're around
I always seem to smile
And people ask me how
Well you're the reason why
I'm dancing in the mirror
And singing in the shower
La dee la da la daaaaaaa
It's actually funny because I met Christina Aguilera and I thought for sure that would be an exciting moment in my life. And I was like, "Christina, my name's Daniel. I sing 'Beautiful' in 'Mean Girls.' And she was like, "Never saw it." And then turned her back and walked away. She was so rude.
