Me, Lol.
I understand your point, and God looks upon the heart first. He is far more pleased with the worship of someone who truly loves Him than someone who can sing but doesn't.
But the thing is, music done right is a reflection of the beauty of Heaven. We exist as many members of one Body, yet all of us exist in
harmony with one another. This is the beauty God created music to reject, and it will serve throughout eternity to remind us of the beauty of all of us having different personalities, different gifts, different tastes, yet all fit together in perfect harmony and build upon one another in the beauty and holiness of God.
I'm a music guy, so don't sing out of key around me. I'll love you, but I'll take your microphone away and give it to somebody else, and tell you to sing your heart out to God, over there Lol.
