My little girl Yana has been through a number of surgeries to treat a significant heart defect. A long road full of struggle for all of us. As we walked this road as a family, there were a few songs that resonated with us as heart songs.

"Be still and know that I am God." - simple and profound message. Especially the second verse: "I am the Lord that healeth thee."

Here are a few hymns that drifted to the surface in these times:
"Great is thy Faithfulness."
"When Peace like a River"
"My Jesus I love thee"
My wife and I have both noted how hymns are often the first songs that come to mind in times of trouble.

Some more contemporary songs that resonate deeply with me:
Be Unto your name
The River
Ancient Words
How Deep the Father's Love for Us
Let it be said of us
My heart is filled with Thankfulness
Blessed Be Your Name
How Great is Your Love oh Lord (No eye had seen)
For the Lord is Good
Here I Am, Lord

I think most of these songs will end up being "canonized." Or at least they will be in my heartsongs list.

And of course there are the joy songs... More upbeat drum music, generally. Days of Elijah, Not be Shaken, the list goes on for a while.
