Cover art for Darkness Between The Fireflies lyrics by Mason Jennings

this song's meaning is pretty clear: it's okay to think about the people that have been with your significant other before you. just don't get too jealous.

also:

fireflies = their love. the darkness = whatever was between their love. clearly one is more lovely than the other, but the darkness between fireflies (on a summer night, perhaps) is also very beautiful and a part of accepting the beauty of the light that the flies give off.
