Lilly allen. I'm not sure how popular she is around here, but she's a uk musician who makes really cool satirical and scathing pop. She puts across a lot of social awareness vibes in really short punchy lines. She seems to have a lot to say about modern bourgoise society and admits her part in it and wonders what a person is supposed to do about it, when things are rigged from all angles to exploite others.
and anyone who has a song about Bush titled "Fuck You" is ok with me.
here's her current single The Fear.
