Classic Country music - please assist

[dmyre]

I am working on a project with some friends, and would like to hear some of your favorite classic country songs. Here's some that we've already included, but are looking for some more.

Johnny Cash - Folsom Prison Blues
Hank Williams Jr - Family Tradition
Charlie Daniels - The Devil Went Down To Georgia
David Allan Coe - underground stuff

My minds drawing a blank, so any other classics would be appreciated...
