The love of music and song was put in us at creation. God loves singing. He loves His people to sing praises to Him!
Psalms 149:1-3 Praise the Lord! Sing unto the Lord a new song, and His praise in the assembly of the godly ones. 2 Let Israel rejoice in its Maker; let the children of Zion be joyful in their King. 3 Let them praise His name with dancing; let them sing praises unto Him with the tambourine and harp.
