As a JW I don't think I ever listened to any Christian music. There were no Christian music stations around, and I never went in any Christian stores that carried the music. I heard the odd song on TV. I always loved the song Amazing Grace, it always brings a tear to my eye and when it is sung really well, gives me goose bumps.
I now listen to Christian music quite a bit and really enjoy it. My mother and sister think I'm a big bad apostate for having those CD's in my house. They didn't like it when I sang along at my uncle's funeral either. I don't care anymore what they think.
