Cover art for Let's Call It Off lyrics by Peter Bjorn and John

this is about a relation ship that has ended and he's talking to the girl and saying "you remember what happened last time we were in a relationship and it didn't turn out so well" and that reason is because they got tired of each other and they don't know why it all failed,or why they just don't feel the same as they use to so..and also they don't want to know. it's like saying let's just kill the whole relationship thing between us once and for all.
