To a Poet Lyrics
you don't want to lose"
I said, "Darling, I'll give you everything I got
if I want them to choose"
far away from you
Though unwillingly I left
and it was so, so hard to do
with the whitest of snow
And they don't make no excuse for themselves
and there's no need, I know
and I will surely break
And every morning that I wake
god, it's the same
There's nothing more to it,
I just get through it
Oh, there's nothing more to it
I just get through it
how dark it gets this time of the year
And how apparent it all becomes
that you're not close, not even near
I have to be sincere
I have a hard time standing up
and facing those fears
"You can't plan on the heart"
Those words keep me on my feet
when I think I might just fall apart
and I will surely break
And every morning that I wake
god, it's the same
There's nothing more to it,
I just get through it
Oh, there's nothing more to it
I just get through it
Oh, there's nothing more to it
I just get through it
just when I needed you
I won't ask again
Because I know there's nothing we can do
Not now, darling, you know it's true

Why is this song named "To a Poet"? Who is this poet? And who is Frank? The omniscient Oracle of Delphi of our time, Google, has all the answers.
"You can't plan on the heart" is a quote from the poem "My Heart" by Francis Russell "FRANK" O'Hara, an American POET (1926-1966).
Here comes a simple story that would match all the lyrics:
While on tour in the United states, "she" (Klara or Johanna or a fictious character) falls in love with a person living there. She knows from the beginning she cannot stay there. When the tour is over she'll have to fly back to Europe. If she could have planned where, when and with whom to fall in love, of course she would have planned it differently, but "you can't plan on the heart". Back home (probably to Stockholm because it's so dark there in winter) she wallows in self-pity because her lover is so far away.
As a matter of fact, when the Söderberg sisters recorded this album together with the "Bright Eyes" musicians in the studio in Omaha, their younger brother Isaac fell in love with Mike Mogis daughter Stella. Klara and Johanna stated this in a radio interview.
A highly emotional song. Makes me melt away each time I listen to it :)

And every morning that I wake ah, there is this ache

I'm about to add this album to my record collection. based on the strength of this song, the harmonies in the chorus are fantastic.
Simply think its about giving up anything for a relationship, and it didn't work. so she misses the person who left, but she knows she has to get over it and move on.
should have more comments, if it wasn't so late i would have written more, and possibly made more sense.
but definitely the overriding theme is one of missing somebody strongly, and being willing to give anything to get them back.
