Seems Kate Nash has got a big following amongst teen age girls, primarily because she's seen as one of them, living their lives and speaking their language.
As an article about her in Q says, her songs "speak to her overwhelmingly female teenage audience in a way that only an overwhelmingly female teenage audience can understand". Or as a couple of 15 year olds put it: "she's a normal girl you can relate to…her songs are really true…and funny…and some of them are just random…it's like a diary"
Shows the power of good storytelling when it comes to engaging people.
And as with the way Lily Allen was embraced, maybe Kate represents a new kind of role model for a generation of young women who have been fed the myth of footballers wives: that the only way to be successful is via vacuous celebrity and manufactured glamour.
As she says about Girls Aloud: "they're like dolls…they're fembots". So there may be hope for the sanity of the world yet!
