I believe the lyrics play a big role...especially since you are a professing Christian. When listening to Christian music, we should feel motivated to rejoice and give glory to our creator. If you're singing about how flowers smell nice and stuff, that's not going to make anyone want to praise God. I always think about those who have never heard about Jesus, but are listening to Christian music. Music is an excellent way to witness and reach out to the lost. How is anyone, who is not saved, suppose to get the message Jesus died for our sins from flowers smell nice?
