I think I can relate to your experience quite a bit. In my younger "carnal" years as a Christian I did not devote ANY energy to music of a religious nature, and only listened to "radio"/CDs/etc which came from the repository of secular roots of my older brothers, namely (first generation) classic rock. After getting serious about fundamental/evangelical Christianity I pivoted to a position of listening to primarily HAC/BoJo/Southern Gospel (The Inspirations was my favorite). In the last 5-10 years I've softened a bit on the militancy issues like music, and do listen to satellite radio genres of music I grew up on, but in doing so I limit that to music that don't have a patently offensive anti-Christian theme. Having said all that, nothing in our culture surprises me anymore. People claiming to be Christians while denying basic fundamental core principles of orthodox Christianity simply mirrors the postmodern turn of a younger generation that can rabidly and radically claim that "you have your truth and I have mine". Couple that rugged and outrageous autonomous spirit is only further exacerbated by the truly radical leftist agendas that easily spread their message through social media. Add in a dose of cancel-culture and young people are afraid to buck the swelling tide of worldliness that swamps them.
