I've started using them again in my car's cassette payer. I've turned off talk-radio, the news, and the sports. I've even been listening less to the Christian radio stations, as helpful as they are. I've just put on my cassettes of soft, instrumental Christian hymns, and I've found that in that environment my mind more naturally tilts toward praying and meditating on Scripture. The fathers and prophets wanted nothing else to be associated as clearly with the Word of God as music.
Music is the handmaiden of theology.
After the Bible, the hymnbook is next. And remember, I do not say a songbook or a book of gospel songs, but a real hymnal containing the cream of the great Christian hymns left to us by the ages. Sometimes our hearts are strangely stubborn and will not soften or grow tender no matter how much praying we do. He should read out of one and sing out of the other, and he will be surprised and delighted to discover how much they are alike. Instead be filled with the Spirit.
