Mostly this is a collection of Buffett songs that are presumably in the movie, with occasional snippets of dialogue from the film. I never care for that practice and it seems especially pointless here. I haven't seen the movie and the selections aren't interesting on their own.

There isn't much that sounds like "score" though there are some instrumental tracks like "The Wrangler" that might be source music.

The instrumentals "Gothic Ranch Action", with synth strings and walking electric bass as well as jazzy electric guitar and vibes solos and "Fifteen Gears", with acoustic guitar and features for harmonica and fiddle as well as country-rock electric guitar, are probably used as score.

The Western swing of "Cattle Truckin'", with its steel guitar solo, is probably also used as score rather than source.

The rest of it is Jimmy Buffett songs and I think they're all really good, well written and well performed country songs with great vocal harmonies and excellent playing from all of the musicians, the guitarist in particular.

Maybe this movie is worth seeing. The music is definitely worth listening to.
