This reminds me of efforts to reproduce Ancient Greek music. [1] It's very similar in that there's a lot of hints, but still enough missing parts that there seem to be two schools of thought, that can even present within the same project. That linked audio is unpleasant, but perhaps they just liked it? Yet, this solo [2], comes from the exact same project - and is amazing.

I do not think tastes can change to such a degree that that first link would ever be pleasant to listen to, though that itself could be intentional for theatrical, theological, or other such purposes. Music seems innate to humanity - children generally start 'dancing' of sorts to music, 100% on their own, before their first birthday, long before they can speak or usually even walk!

The thing is that even if we do not personally like some form of music, I think we can still appreciate it. The Chinese guqin [3] is my favorite example - it goes back at least 3000 years, is played in a fashion completely outside the character of modern music - to say nothing of Western musical tradition as a whole, and yet nonetheless sounds amazing and relaxing even to a completely foreign ear.

Culture and tastes may change, but I think our ability to appreciate (or be repelled) by things is fairly consistent.
