"Weightless" is a song by Christa Wells which quickly became one of my favorites. Christa gave permission to Tim Challies to publish it on his blog as a free download.

The song is about repentance and forgiveness. Here's the complete lyrics:

Nothing scalds
like the memory of wrongs
I did when I was young.
How could I? How could I?
I'm sorry

I see the eyes
of the ones that I
so carelessly abused.
How could I? How could I?
I'm sorry

Well, I've carried this a long time
in a well-hidden bundle on my back
but I've realized repentance is weightless
so I'll leave my burden on the tracks

And then I face
the yesterdays that disappointed,
misunderstood by a cruel world
and I'm angry

You might suppose
the years would close the curtains on a scene
from such a time, but this was mine to harbor

Well, I've carried this a long time
in a well-hidden bundle on my back
but I've realized forgiveness is weightless
so I'll leave my burden on the tracks

It's gonna be like delivery
that's overdue and getting too heavy
Then suddenly,
I'm weightless
