Cover art for Dragon Queen lyrics by Yeah Yeah Yeahs

The song is about Heroin addiction. Hence the tile Dragon Queen... as in "chasing the dragon" which refers to chasing heroin to get high.

My mouth you're touching Your mouth is running No loving for nothing Nobody knock my body out -----Talking about getting fucked up, love for money... getting so high you're knocked out

My mouth is blowing right off I'm so gone Incoming, out clubbing Not loving, slow your body down -------Talking about doing cocaine

How are you not going to show your scar? How are you not going to get high, high?------Talking about keeping the addiction a secret.. "show your scar" track marks..

My Interpretation
