Cover art for Sweet#hart lyrics by Closure In Moscow

I think it's about a guy who is trying to convince his girl to have sex with him but she doesn't want to just yet (I'm dying to feel what you feel now, you've already been such a sweetheart, and I know we all get scared, we all get scared).

The part which shows the girl is scared is: Because, lover, lover breathing down my neck Incendiary breath And still my lover is a burden Tell me something could you smell my fear? As I lay there Cringing on your bed

It boils down to "too much head, too little heart," which, as someone mentioned, is probably the prevailing theme of the album -- his ol lady is thinking too much about the situation, instead of letting her heart into the equation.
