speed up a song, heighten the pitch, and slap a hot anime girl in the background

It is not necessarily higher pitch than the original, it is just tweaked in any way to improve on the original as much as possible, the video must be enough to tell a story, a moving image with a good song is actual Nightcore , while high pitching a bad song over a anime pdf from google is not Nightcore in any goddamn, that is the work of people trying to benefit of being related to the Nightcore Covers fame. It is also not after the Norwegian band, just un unlucky coincidence. Nightcore means remastered songs, there are also many Nightcore bands because taste differs and that's OK. They are not greedy weebs because hardly ever a good enough song doesn't have copyright, I have a completely demonized Nightcore channel, it's a nice hobby, also any true Nightcore fan shows they just can't help but fix things, like OCD for good quality stuff.

Probably one of the saddest excuses of a genre, nightcore is a type of music that is a piece of already existing music sped up or pitch shifted, making it questionable if its actually a genre or not, though a genre would assume that is purely made up of original songs. In its history, people have said that it is low effort and requires no talent other than the ability to pirate music and use windows movie maker.

It's music that get sped up by childrens and teenagers period

The best up-beat music ever! With anime picture covers, and amazing voice meddiling,its perfect for someone who listens to super fast music.

Music that is basicly sped up (Even the vocals so it sounds like a fucking chipmunk)
and a hentai/anime pic to make the kids horny so they click the video

The practice of making any given song sound more Japanese by raising its speed and pitch.
