the title of the song basically sums up its meaning--that he feels absolutely no emotion up on that stage. the side-theme, where he says "don't come with me tonight, if i said i cared for you i lied" is about if a girl were to follow him, hes warning her that it would only end up in meaningless sex and he would toss her aside afterward and forget her, like so many band members are famous for. the follow-up, "you waste no time tonight, you'll take me home if it costs your life" is showing that the girl basically doesnt care and she'll do anything to get in bed with him.
