Nothing special there. Sounds like one of those Morissette clones. She needs to take some vice lessons. Maybe with a little practice and sobriety she could sing back up for Ann and Nancy Wilson, Christine McVie, Pat Benatar, and Grace Slick. ( I am only considering rock acts here less we’d have to name about 100 other girls acts like Aretha, Tina, Reba etc... )
From the sounds of things she's got quite enough vices that she's good at to keep her going.
