What are your favorite horse songs?

I'm putting together our annual horse-camp music play list and would like to update it with some horse songs. I've got all the old standbys, like Strawberry Roan, Tennessee Stud, and my personal favorite, The Bucking Song by Robert Earl Keene. Also have pretty much anything Chris LeDoux and The Rodeo Song. Does anyone out there have any other suggestions? You would be making some trail riders very happy!
