As I walk through life I have life experiences. Those experiences inspire me to make music that reflects what I am going through at the moment. It can be the moment of worship, a story, a painful experience I want to share or a joyful moment. The story can be expressed through a song that has words or through a collection of sounds called music. Although I understand you desire to have more music that contains scripture or worship lyrics it shouldn’t be a requirement for an artist to be called Christian. An artist is a Christian if he is filled with the Holy Spirit.
