The great orators, such as Spurgeon, have studied them. World leaders still quote them. In other words, the artistic abilities of Paul were not to draw attention to the artist. They were to bring men and women to a personal knowledge of the power and glory of God. Music that produces worship will be participatory in nature.
True worship has no room for a spectating heart.
Worship cannot sit in the grandstands of the church watching the performance of the more talented. You, O God, have filled me with a knowledge of Your love. And You alone must I worship. True worship does not perform for others. It only participates in the grace and love of God.
