There’s a song being played during the dance scene at the cowboy bar. Female vocal. Something like “he’s got the money....”?

How can I find or purchase ‘half empty’ by Keith Gattis. This song doesn’t appear to be on the Sicario soundtrack

I just watched sicario for the second time, because it's a fantastic film. But the next to last song in the entire film is just a beautiful song for the guitar. But I can't seem to find it on this list. Can somebody help me out?
