Cover art for Night & Day lyrics by Moondoggies, The

I personally think it goes "And I believe that your heart is like a butterfly" but that's just what I hear. I think that because this song sounds like it talks about loving and knowing the love its good for you. So a butterfly (who flies erratically) would make sense for someone that isn't good for you. Again just what I hear.

I meant isn't good for you, but ya know.
