Looking through my mp3 player, it's 100% secular music. Mostly 90s alternative, classic rock, and rockabilly/horror surf music.
This has gotten me grief from Christians over the years. Has that stopped me from listening to my choice music? No. I listen to it more lol.
A lot of Christians say interesting things but you have already forgiven them.
A lot of times it has to be their way or the highway while they're condemning you to Hell for something they don't like while saying stuff like "I'm saved even if i kill somebody".
So enjoy the music, forgive the confused and be grateful to God for everything in this Earth including hearing the music, smelling the flowers, tasting the food, enjoying the beautiful sights of nature and everything else in-between.
When you know the difference between addiction and gratefulness there's nothing in this Earth that should shake you.
