Cowboy songs so far

There are a lot of songs known as cowboy songs. So far, I know the chords to Home on the Range, My Darling Clementine, Red River Valley, and Ghost Riders in the Sky. Memorizing the lyrics, however, is going to take some time. Next on the radar are El Paso, Back in the Saddle, and Jingle Jangle. These songs tend to have simple structures with just a few chords and have melancholy or even morbidly sad lyrics.
