From their second album Hold Me Down, You Me At Six have shown that pop-punk isn't just for the faint hearted. The second album has an edge to it which lacks the self-consciousness of the first, and this is never better demonstrated than in this song. The melody it has to be said is a YMAS standard, but with a couple of very interesting twists - the end of the bridge for example is what I can only call a 'musical win'. The lyrics remonstrate with an ex-lover for a relationship which seems to have been a game of kiss and tell. 'This love is dirtier than you think,' the song warns, and I'd have to agree with that - Contagious Chemistry paints a picture of love when the rose tinted glasses lie shattered on the ground.
