Nope, I also support only a specific amount of Nightcores. I'm a producer and can tell you the difference, in these kind of song you don't do anything, it takes hardly 30 sec. It's just increasing the speed and pitching the song high and adding reverb sometimes. If you wanna listen to actual Nightcore then watch 'heiakim'. Actual Nightcore is when you spend up and pitch up the singer's vocals and change the background entirely and make a complete new song with new drop. Not just taking someone else's work and pitching it high.
You can hate them all you want. But there is a point in what they are saying. "nightcore is the song sped up." it doesn't need any effort to make, but at the same time it can be used without any copyright issues. And that pisses many people off, they are not wrong in that.
@Major Rafa Nightcore is a sped up and high pitched version of a song but that doesn't mean that you just pitch the original song high. This is a 30 sec. Work. Take all his hardwork, pitch it a few semitones high and now people will say you made Nightcore. Nightcore are remixes, that is, you make the remix of a song but using the vocals pitched and sled up than the normal 💁 not just pitching the original.
