...even though you KNOW they are the wrong lyrics.
One that comes to my mind: "Possible Maybe" by Bjork.
In the chorus she sings "Possibly maybe, probably love" but I've always sung it as "Possibly maybe, possibly not."
I don't know but I always like it better that way. It just makes me happier, even with the word "not". does that make me weird. lol?
anyways, do you have any songs like that?
