Late grandmother listened to country music. It had to be country too if she had control of the radio so, no, I couldn't listen to any pop, rap, hip-hop, anything of that sort (unless I wanted to play it in another room). Also, when she got drunk, it had to be full volume too, and I mean FULL VOLUME. I'm surprised no speakers were blown out in the process since you could hear it from across the street, if not maybe further down the street. I remember losing sleep and crying about it one night because it was just that loud. Not that my grandmother meant any harm by it, and I think she did dial it down some, but that's how it went in my grandmother's house when she really wanted to listen to music.
My late grandfather no doubt was also into country music since it runs deep in that part of my family, but he was into producing his own music as well, mainly gospel music. I think I have a CD he produced laying around in my closet, but sadly a lot of the music he recorded (along with a lot of other family related memorabilia) has been lost by now. He played guitar and did vocals pretty good, and I do remember him coming to visit the rest of us in Texas and playing a few of his own songs which was a pleasant treat.
The rest of us - my parents and their siblings being Gen X, my cousins and siblings being Millenials/Gen X - we're not that big on country music as our grandparents were, so that didn't rub off on us. I personally do listen to some country once in a while, but I prefer a wide range of genres these days.
