Query: Decent product, but could be better.

Although the narrator speaks clearly on the CD and is easy to understand, he has a sing-song voice which tends to put you to sleep. The audio mix leaves much to be desired; I have to turn the base all the way down and the midrange and treble all the way up on my car radio in order for the voice to sound somewhat natural. I have listened to many books on CD from Recorded Books, who employ professional actors/actresses as narrators, and that is the standard to which I am comparing this product. Zondervan could have put a little more money and effort into this product. After all the scriptures do say: "Whatever you do, work at it with all your heart as working for the Lord, not for men, since you know that you will receive an inheritance from the Lord as a reward. It is the Lord Christ you are serving." (Colossians 3:23,24)
