Christian music is sung to the Lord, not for the world.
1 Chronicles 16:23 Sing unto the LORD, all the earth; shew forth from day to day his salvation.
Psalms 13:6 I will sing unto the LORD, because he hath dealt bountifully with me.
Psalms 7:17 I will praise the LORD according to his righteousness: and will sing praise to the name of the LORD most high.
Psalms 33:2 Praise the LORD with harp: sing unto him with the psaltery and an instrument of ten strings.
Psalms 147:1 Praise ye the LORD: for it is good to sing praises unto our God; for it is pleasant; and praise is comely.
Isaiah 42:10 Sing unto the LORD a new song, and his praise from the end of the earth, ye that go down to the sea, and all that is therein; the isles, and the inhabitants thereof.
Isaiah 12:5 Sing unto the LORD; for he hath done excellent things: this is known in all the earth.
Ephesians 5:19 Speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord;
Colossians 3:16 Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord.
Why does contemporary christian music appeal to the world? Because it feeds the flesh and carnal mind—the music gives you an emotional high, like rock music(which is what CCM is). On the contrary, Christian music feeds the spirit and the world will not worship Him in spirit and in truth.
John 4:23-24 But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him. God is a Spirit: and they that worship him must worship him in spirit and in truth.
1 John 2:15-16 Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him. For all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world.
James 4:4 Ye adulterers and adulteresses, know ye not that the friendship of the world is enmity with God? whosoever therefore will be a friend of the world is the enemy of God.
Romans 12:2 And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
