All those ideas are man-made and led to the problem we're having today with the proliferation and rise of false tongues.
The most important thing is if the tongues is genuine and that it's the Spirit of God that gave the utterances, once that happens everything else is secondary because Spirit of God knows well what He's doing better than any human and is much more capable, so it's bound to produce results just as it did in the day of Pentecost even though we may not know it.
Therefore that's what we should focus on not the man-made idea of edification or whatever.
I disagree with what you said.
The gift of tongue should be for edification of the church. Demons and witches do speak in tongue so we need to be care on songs we listen to.
As for me I don't listen to songs that speak in tongue (as I'm been lead by the spirit of God).
Those song can bring a spiritual Christian down. Be care.
