Second verse slapped harder than expected.
And on the topic of nightcore being art or not; who cares? Art doesn't have to be this totally involved thing for every person's every project. Making minor alterations to other people's work is its own style and form of creative exploration and, if encouraged and engaged with sufficiently, can easily grow into something with more luster and prestige. And besides that, some songs do just be sounding better when played faster and higher than intended. Artists or not, good on em for playing around and finding the ones work.
I am of the opinion that once a piece of art is shared with the world, it stops belonging solely to the creator and instead becomes the property of the community. I also know how hard it can be to just barely scrape by, so I don't personally have a problem with people making low effort money in this way. It is a bit scummy to piggyback on people doing actual skilled work, but at the same time, so is much of the world in far more direct and brutal ways.
Other than that; agreed. It feels like one of a few next logical steps for that sort of og YouTube fandom energy. If it inspires joy and isn't hurting people, I say let em at it
