Cover art for The Mixed Tape lyrics by Jack's Mannequin

I have to comment on the gf->enemy thing. So after spending all this time in the relationship, you get close and something happens that splits you. It doesn't have to be one thing you can point to, maybe you grew apart. Now when people talk about how similar the two of you are you don't want to hear it because it hurts. You know that some difference is big enough to split you up.

Then he has the line: You said you meant it there's a piece of me in every single second of every single day

She still thinks of you, and you her, which is shown in the lines: It's when I spend the most time Thinking 'bout what I've given up . . . . . when you start the day just to close the curtains you're thinking 'bout what I've given up

Whatever it is that was given up ended it all. Then the last lines I'm cutting through you track by track I swear to God this mix could sink the sun But it was you I was thinking of

These lines make me think that the mix isn't for her as in to be given to her. It is for her like a dirge or an epitaph. It covers that part of your life that was hers. A story to tell the children about a love that was, but isnt.

This song is so powerful. It's like I wrote every note with my own finger.
