When your Country stations are playing Marshmello - Miles On It and A Bar Song, and Morgan Wallen releases songs with hip hop tracks instead of guitars, the line between pop and country is blurred more and more.
The country stations are also playing Cody Johnson, Carly Pearce, and Justin Moore. The Garth Brooks duet with Ronnie Dunn is very country. So is the new artist Zach Top. Country stations have learned to offer a wide variety of styles rather than a narrow niche. Music listening doesn't always follow neat radio formats. That may be why some formats do better than others.
