I personally love to hear people using talents that God has blessed them with, playing instruments of all kinds, lifting voices of all timbers, blending together in harmony, rhythm and beauty, singing praises to our God! It uplifts the soul.
Many fear the emotion that music stirs, believing emotions are sinful. Yes, some of them are, yet I do not believe the Lord would have us be emotionLESS. God gave us emotions and feelings, and while we should not depend on them, we can certainly thank the Lord for them.
From my experience stiff, staid music with no joy, life or spirit can be just as destroying to the Church as the worldly influences of rock-n-roll.
A hymn rich with doctrine, a psalm or a simple chorus... hey even a spiritual song!... lifted up in voice alone can be just as beautiful, spiritually encouraging, exhorting and uplifting as a full symphony choir. But the main ingredient to any song sung for the glory of the Lord is a heart dependent upon and in tune with the moving of the Holy Spirit in the lives of the people.
