In 2004,Ashlee Simpsonwas primarily known as a little sister.
As a teen, Ashlee was famous by proxy.

It was because of this opportunity that Ashlee got her first record deal.
She spent 2003 recording what would becomeAutobiography, an album that turns 20 this week.
Instead, she fit herself into a post-Avril Lavigne musical landscape with ease, writing confessional guitar-driven cuts.
Her voice had a distinctly edgy rasp that she yelped out those scream-along lyrics with.
Meanwhile, power ballad Shadow addresses the anxiety of sharing the same ambitions as an already-famous sibling.
