Well, this is weird. Spotify has a 12 song version of Cass County available. (I'll have to check again to see what songs are missing). That's the first I've seen or heard of a 12 song version! Luckily, they have the normal 16 song version listed as the "deluxe" version.
ETA: songs missing from the Spotify 12 song version:
Too Much Pride
She Sang Hymns Out of Tune
The Brand New Tennessee Waltz
Too Far Gone
