Ok, now this is exactly like one of my family discussions.

Could someone explain what and where exactly are these insurmountable sound problems?
For now it's only been named the compressions of the vocals, which didn't bother me at all personally.
And what is the difference between engineering problems and production problems? Isn't engineering part of the production?
