Hey, it's the crap I hear at 24 Hour Fitness!
My late great best friend had a job with a long commute from 2000-2006. So he got satellite radio and listened to a bunch of different stuff. If something really got his attention, he'd go to the local Borders and could usually get the album that it came from. He got particularly into alt-country, which I suppose was a little unusual for a Japanese guy.

Stuff like James McMurtry and Junior Brown (and his distinctive custom guitars), just off the top of my head.
