I thought that was the Salvation Army back about 150 years ago when they were accused of using “Common” tunes for music.
“Why should the Devil have the best music?”
We have come a long way from St Paul’s admonition “Let all things be done decently and in order.”
When the worship session is over, the sermon begins, without the music interfering with the message. In my church, with loud music, we had over 400 people coming to Christ last year. Evidently the music isn't interfering with the message of salvation.
And as for the context of 1st Corinthians 14:40 (that you referenced, I ask you to look at the prior verse).
1 Corinthians 14:39-40 (AMP)
39 Therefore, believers, desire earnestly to prophesy [to foretell the future, to speak a new message from God to the people], and do not forbid speaking in unknown tongues. 40 But all things must be done appropriately and in an orderly manner.
Even though Paul had spent much of chapter 14 fussing about tongues being abused and taking precedence over the message, in verse 39 he says not to forbid tongues altogether (earlier in the chapter he said that tongues is good because it edifies the individual, so it's good, just not as good as a message edifying everybody). It would seem the same would apply to music in church. Don't forbid it, just don't let it take precedence over the message.
Ironically, the ones who would say loud church music violates Paul's 1 Cor 14:40 “Let all things be done decently and in order" admonition tend to be the last churches following Paul's teaching in the prior verse: "Therefore, believers, desire earnestly to prophesy". LOL
