Writing music for Scripture songs is not for the faint of heart and takes an acute skill. There must be sobriety when you handle the text of Scripture. Namely, it is difficult to have literal faithfulness to the text, and still create pleasant and sensible structure to the music. Adam Wright demonstrates just that again in Psalm Songs: Volume II. The music "makes sense" and engages you with joy and purpose, and truly brings the Scripture alive.
Prayers of the Saints has managed to beautifully capture the sojourning believer's sense of longing and anticipation.
