briefly played song in season 2

This is driving me crazy, so I come to you in desperation. Maybe somebody can help?

In season 2, episode 5, Hemlock Diego's Policy Player's Dream book, a song is playing quietly in a brief scene where destiny is in her kitchen with her boyfriend, cooking up the hallucinogens to break the mom out of the jail transport van. I really would like to know what this song is!

It's bluesy sounding and the only lyrics that I can make out are "baby I can't see. I can't see." And "I'm going down." And "baby, up and down." A Google search for those yielded nothing. Same for a search for a song list. One site did have a song list, but it has this song listed as Old Evil River by the Limes, a different song which actually plays in a later scene.

The song I'm taking about doing very similar to the end credit song, but it's not the same song and from my searching it doesn't appear to be the same artist? Not sure.

Anyone have ideas, even on where else to look?
