Were you trying to be particularly whacky on The Moon is Made of Cheese (but I can't taste it)? The chord choices and melodies are pretty flippin' crazy. Sometimes when I write songs with crazy chords and odd time sigs, I find myself becoming desensitised to the craziness and it all just sounds normal. Does this happen to you?
ah, that's one of the reasons you need to either take longer breaks, or write faster. depending on how much time you think you have
