Just listen to it when you’re alone. That’s what I do. Good point not to play some things to your (young) kids. But I sometimes like to listen to music which lyrics I don’t necessarily agree with. Or from artists that haven’t been exemplary humans. If I like the song and it touches me emotionally and I’m able to differentiate between that and real life, I don’t think it’s bad (for me).
Edit: I’m not sure how ‘controversial’ the song you mentioned is. It celebrates southern music. And country, bluegrass, rock etc had a good amount of impact on the world. Same with the bands they sing about who have influenced music as we know it today. I don’t see an issue with this song.
And if you ask me, let your kids be rebels against injustice and outdated and narrow perspectives on the world.
