I just have a little rant about posts in the audio portal that I have to get off my chest.
The majority of "Hardcore" songs posted aren't actually in the hardcore genre. Most of them use major/augmented keys, which would make it either "Dance" or "Happy Hardcore" or maybe even "Hardstyle" (seeing as how nobody can seem to agree on what hardstyle actually is). Hardcore uses mostly minor/diminished keys that makes hardcore what it is.
Another major separation between "Dance/Techno", "Happy Hardcore" and "Regular Old Hardcore", is the use of drums. Especially the bass kick. Dance/Techno is known for its Uhn tis Uhn tis Uhn tis 4/4 beat that's usually 120-150bpm. Happy Hardcore is typically the same, except the tempo is typically much faster and the bass kick is more articulated.
Hardcore, however, puts stupid amounts of emphasis on the bass kick. It normally has so much distortion and squarising effects piled on it that it doesn't even SOUND like a bass kick anymore. It crazy, crunchy, and it eats babies. Thus, somebody decided it was fitting to call it "Hardcore".
I mean, I'm not a music expert, but this is just what I've been taught by other Hardcore DJ's and what I've personally noticed from listening to popular artists of these genres.
So, please. Don't make a song that makes me want to dance with Barney the Dinosaur and call it "Hardcore". I mean, if you REALLY want to, then at least refrain from flipping out on me and calling me a SuperFatCow when I review your song and tell you it's not actually hardcore and suggest adding distortion to your bass kick.
