I.e has the memeification of this album rendered a disseminated quality akin to the folk music of past?
Surely a folk song in the traditional sense has to be truly popular. What percentage of people in the UK or America would even vaguely recognise a Neutral Milk Hotel song? I think it can't be higher than 5%. Obviously it's a meme in /mu/sic circles but that's all it is, which means it's only folk music if the Folk under consideration is the international diaspora of /mu/tants. And actually I am quite amenable to the analogy between real life nationalities and internet 'national' identities. But such a consideration is a necessity for your claim.
Imagine not being able to listen to a piece of music without five layers of self-reflective internet irony preventing you from hearing the plain truth. Log off OP.
OP is an irritating nu-soyboy who lived on the East Coast of in the Midwest, wakes up and immediately grabs his phone to start spamming /pt/ with his abysmal takes, rehashing the same conversations others had a dozen years ago for no discernible benefit other than to appear 'esoteric' in comparison to his Tiktok peers. I wish he would go back to Valorant or whatever the pudgy angry boys are playing nowadays.
It's nothing like folk music. It's also one million times more brilliant than its retarded detractors claim. Genuinely one of the few popular music masterpieces of the last three or four decades.
