her name is amanda ghost. and that's how an article i read about her described her. i don't know that i hear stevie in her voice, but i do in her style. i quite love the three songs posted on her site. she co-wrote "you're beautiful" with james blunt (try not to hold that against her if you hate that song). what do you all think?

on edit: okay, the second song on this site has some definite stevieness in it, now that i listen again. i'm really loving her. and... just found her first album "ghost stories" on iTunes!
