You don't need to speak Swedish to "get" this song. It's what I should have said to myself many times. Now when I think of some other women I know (young and old) who have invested (in my opinion) way too much time, effort and energy trying to keep a Dead Horse of a relationship going, I think of this song. It is relevant for men as well, but it really speaks to women.
Music can say so much: to speak to the heart and of the heart. I love upbeat music, but there's nothing like a great love song or a "cry in your beer" song. In this case, it's more like a classy bar at closing time after too many Scotch whiskeys.
