Magnetic Fields cd:"Distortion"up-date July,31,2009

I wanted to add some other comments about one of the songs. That song is
"Too Drunk To Dream", there are several references to God;such as,
"and God knows that ain't cheap". In that line,the word God is capitalized
but in another line God is not capitalized and that line is,
"Oh my god,where did I go wrong"?
Furthermore, the last two lines of the song are a refrain of the line,
"and God knows that ain't cheap".
I'm confused,is it just a typo or something else like a hidden meaning
considering that Stephin Merritt doesn't believe in God. I am basing
my opinion on the content of some of his previous songs which
clearly indicate that he does not believe in God.
