Crossword puzzles
Don't seem to solve themselves

Like down by the river
You don't seem to be yourself

Pick of the litter
Never seems to get left out

And I could be crazy but
Well I could be crazy but

I don't see anyone knocking at your door
I don't know anyone that crazy anymore
I don't see anyone knocking at your door anymore

...

Crossword puzzles
It seems I'll never finish one

My cards on the table
But it seems your horse has won
(and all the rest, and all the rest, and all the rest)

And the rest of the details
Seem better left alone

And I could be crazy but
I don't think I'm alone

I don't see anyone knocking at your door
I don't know anyone that crazy anymore
I don't see anyone knocking at your door
I don't know anyone that crazy anymore

...

I don't see anyone knocking at your door
I don't know anyone that crazy anymore
I don't see anyone knocking at your door
I don't know anyone that crazy anymore

Really simple song in Cmaj, medium tempo acoustic. Think City And Colour or Jeff Tweedy maybe. C4C.

I like it. (The description of the key and style helps too!)

The way I'm reading it, this person (that you're singing to) is the one who's used to being the "pick of the litter" but isn't so much anymore? I'm not sure what exactly "down by the river" is, but it's the kind of phrase that evokes enough (at least for me) that I don't need to know exactly what you're thinking of, and the listener can fill that image in with his own experience.

I like the start of the second verse(ish), with "cards", "puzzles" and "horse" all together.

Good stuff!

Thanks for the crit, I didn't think I was going to get any comments!

It's not about something in particular, but I like that interpretation. Most of my favourite songs I have no idea what they're about, I just like the way the words sound.
