I need help figuring something out.

So I found this song and I am almost 70% sure the song is made with AI but I would like to make sure. I have no way of doing that my self though so I thought I could ask here. The song in question is this one: https://www.youtube.com/watch?v=EmdIGN8omSw

It seems apparent that the image they use for the song is AI-generated but tbh the song doesn't sound half bad, I don't actually want to support this though if its AI. I found the Lyrics they used and maybe with those you guys could tell me if they are remotely sensical, the creator of the song claims these Lyrics are in old Norse but I chucked them through a translator and the translator says its Icelandic. Here are the Lyrics:

Hrafnblá nótt liggr þögul yfir haugi.
Djúpur kvíði rennur um moldina.
Forni gæslumaðr andar kaldri andrá.

Vaknar hann úr grárri mold.
Augun glóa sem glær eldstrá.
Ryk og rótir falla af herklæðum hans.
Draugr gengr upp úr jörðu með stirðum skrefum.

Brjóst hans bergmálarr með fornum reiði.
Kaldur andi fyllir loftið.
Haugrinn kallar á verndara sinn.
Hann svarar með djúpum urgi.

Ófriðar gestir kvíslast um nætur.
Hendur þeirra rífa torfið.
Draugrinn reisir sig hátt.
Reiði hans breiðir sig eins og fallinn stormur.

Í augum hans lifir forn drótt.
Eiðar halda hann bundinn við haugsins ró.
Þeir sem trufla sofandi anda
heyra jörðina sjálfa svara.

Draugr gengr yfir rústir nætur.
Hann fylgir skyldu sinni með köldum vilja.
Sál hans hvílir eigi.
Haugrinn er hjarta hans og helgi.

Do they mean anything to you guys? Is this proper Icelandic or did they just write english lyrics and translated them to something that might sound like old norse and then threw that into an AI-Music program to make a song?

Help would be really appreciated.
