I've built playlists on Spotify with everything from Rock-A-Billy to early 70's. I also really like a Library App we have in WI and listen to books, lots of books. John Sanford, Micheal Connelly, Lee Child, Tony Hillerman, David Baldacchi, Rex Stout, etc. I used to use audio books to shut up my transportees before I re-retired. Worked like a charm. We'd get to the joint and the inmate would ask, "How will I find out how that book ends?" I'd write down the title and author for the inmate. So there we'd be transferring custody to the institution and the guards are going through the inmates very very limited property and they'd ask, "What's this?" Looking at the little slip of paper and of course the inmate would tell them. You should have seen some of the looks I got. Nice quiet, peaceful drives of a couple hours without all of the crying and whining about how nothing was their fault, or how mean the DA is, or any of that typical conversation through the cage.
