The guy who gave us ROTMs/exclusives from Loretta Lynn, Townes Van Zandt, Dolly Parton, Willie Nelson, Cody Jinks, Sturgill Simpson, Tanya Tucker, Colter Wall, Joshua Ray Walker, and Paul Cauthen. And also has shown he's a fan of Garth Brooks, Sam Hunt, Maren Morris, Luke Combs, etc.
I think we can expect a diverse set of albums from all flavors of country, one of the reasons why I think he's the right guy for the job. I would be shocked to not see some good 90's country in there. Especially given you can only pick one album each from the heavy hitters of the past.
