Art is subjective, and if you consider her warbling and oversinging art, then
1. Has she done any work for Disney?
2. Why not?
3. What does she have against a first class operation like WD?
I like a few of his/her songs. "Why" features strong vocals, no doubt.
But that "If I Could Turn Back Time" song where she sings half naked to the sailors on the aircraft carrier is Over The Top (meaning outrageous, not the sly Stallone movie

)
I'll be that if she could "Turn Back Time" she'd not spoil her artistic intergrity by doing the video !! LOL OMG
Bottom line: I'm not gonna give her a chance.
