I like it loud so I can sing my heart out and only God can hear me. I too am a “joyful noise” singer, LOL!
I personally love to hear voices joined together in worship. I like harmonies - in fact I like the MoTab Choir. Maybe it comes from my years growing up in Mormonism.
I’ve heard others say the opposite, that because of the years spent in Mormonism - they can appreciate the loudness and joyfulness of a rock band.
That’s what is so great about Christianity. If you don’t like the style at one of His church groups, you are free to attend another. Jesus doesn’t care how you sing, only that you do. :D
