Yes, certain music need a bite on edges, but it needs to be the right bite on the right edges.
Definitely a lot of recordings were not meant to sound real so there’s no way to get it to happen. Still, they can be quite enjoyable.
As for "good enough," I consider it good enough when the fundamental issues of the recording and playback method are the major constraint, and issues with things like max volume and frequency response are already beyond anything I want happening in a home setting. If I’m just doing 2 channel, 2 speaker stereo without some way of dealing with inter-aural crosstalk, I find that point of "good enough" happens pretty quickly. No point in trying to upgrade components when I’m just going to be heavily distracted by the crosstalk anyway. I know that not everybody is bothered by it. There are many ways for a system to sound good, and some people can filter out or psycho-acoustically hear through issues that I can’t.
I suspect that a lot of music lovers who aren’t audiophiles are exceptionally good at re-constructing what’s missing or distorted in the playback. They don’t even know they’re doing it, so they don’t get what all the audiophile fuss is about.
I can say for certain that I’m not the one you want adjusting photos or color grading video, or mixing and mastering audio for professional production work. I watch videos and read books on what’s supposed to look and sound good and what’s not, and I often can’t see or hear that anything has meaningfully improved. I usually prefer they just leave it all alone unless something is obviously off.
I do wonder about the effort put into mixing and mastering a lot of pop music. Does it really significantly increase sales?
