6. "Lonesome, On'ry and Mean"
You go ahead and tell Jennings that "ornery" isn't spelled that way. Though written by Steve Young, the pen behind the Eagles' evocative "Seven Bridges Road," "Lonesome, On'ry and Mean" became Jennings' theme song, summing up the way the seminal outlaw went through at least part of his career. Never released as a single, the song was the title track to his acclaimed 1973 album, as well as the lead-off track to 1979's multi-platinum Greatest Hits compilation. Covered by everyone from Travis Tritt to Dierks Bentley, "Lonesome, On'ry and Mean" remains testament to Jennings' wild, wandering and, at times, exhausted spirit. Listen to him sing the line "there's no escaping from his snowy white dream," and your own body will ache.
