I will add to this thrilling thread.
Probably Regina Spektor, as a whole package. Amazing voice, amazing piano skills, amazing live performances, amazing song composition, great lyrics, and fantastic person.
Favorite female singer right now is probably Dee Dee Penny from Dum Dum Girls. Just saw them on Thursday for like the 4th time. Forgot that she sounds just as great live as she does on the recordings. She writes all her own stuff, I haven't heard a song by her I haven't liked, and in the long run she's gorgeous to boot so there ya go.
fuck fuck shit fuck
