I agree with the Death Before Dishonour part. They don't sound like a regular heavy/thrash metal band.

Knuckle Dragger's genre is fine, except I think Hardcore should be added to the tag; their three releases prior to the new ep were very hardcore, and less so death metal. So "Powerviolence/Grindcore/Hardcore/Death Metal."

Agoraphobic Nosebleed's genre is fine except Cybergrind needs to be added to the Grindcore tag (Cybergrind/Grindcore, Sludge/Doom Metal). They play more straightforward grind on Honky Reduction and Agorapocalypse, but are far more on the electronic cyber side of grind on Frozen Corpse Stuffed With Dope and--especially--Altered States of America.

Full of Hell's genre makes sense, somewhat, but they definitely play powerviolence and noise on their newest album. Might it just be better to condense the genre to "Powerviolence/Grindcore/Death Metal, Noise" (since the noise is played separate from the main genre, such as single tracks or segments of songs, or like the full EPs) and write in the notes that they shifted to a more deathgrind sound on their last two albums?
* https://www.metal-archives.com/bands/Fu ... 3540438869
* https://fullofhell.bandcamp.com/album/weeping-choir (noise and powerviolence)
* https://fullofhell.bandcamp.com/album/t ... ng-ecstasy (no noise, but powerviolence)
* https://fullofhell.bandcamp.com/album/a ... eavy-light (I know this was a one off collaboration, but it is definitely "noise" and "powerviolence" to describe the later genre)
* https://neurotrecordings.bandcamp.com/a ... ike-i-ache (Another one off collaboration that fits the noise and powerviolence in the later style)

I've also seen that Slam has been added as a genre, and here are four band's that fit this tag:

I'm not really sure why Noctem has thrash in their genre; they've just sounded like Melodic Black/Death their entire discography.

Spirit Possession sounds like first wave black metal, so I think Black/Speed Metal fits them better because they certainly aren't pure "black metal."
* https://www.metal-archives.com/bands/Sp ... 3540462766
* https://spiritpossession.bandcamp.com/album/2020-demo

Inhuman Nature is definitely defined as "crossover" on their new album. They have some crossover elements, with more hardcore elements on their first EP; vice versa on their new album. So, Thrash Metal/Crossover/Hardcore should be fine.

Tore Fagerheim is an artist I've been meaning to bring up for a while now. His full length album, which got him accepted, was pure Melodic Death Metal; however, he needs additional tags. He ventures into pure Metalcore at times. He also has many singles, of many different styles. I think his genre needs to be extended to "Melodic Death Metal, Metalcore, Various." I think the comma works better because he ventures between the really melodic melodies and then into harsh palmuting; not really musically combining the two at the same time.

Also, I think Rambo Hates Rainbows needs a slight addition, too. They released a Noisecore album in the middle of their discography, so "Black/Sludge/Doom Metal, Noisecore, Electronic." Of the few releases they have, it's the only other full length and the second longest release, so it's a legitimate style they've played. I can't find the first demo, but it included all three styles as well separately.

I saw it go back and forth in the rejection forum and thought they sounded interesting. It was originally uploaded as Black Metal/Black 'n' Roll then changed to Black Metal/Punk. Both are technically right, but accurately it's Black Metal/Crust 'n' Roll. It definitely has B&R elements, but leans more toward black metal with punk/roll elements. It sounds like Black Panda/Hejtman (who are actually on this site as crust 'n' roll) with black metal.

I'm really sorry about this one, guys. Picha's early tag is mildly incorrect; the grindcore/noise early tag as it is would be accurate for a band like Full of Hell or Hatred Surge, but these two releases merit it two different genres: Noisegrind/Gorenoise. Both are uniquely different and are heavily incorporated in both. The noisegrind aspect of it incorporates heavy noise over grind riffs while having an odd uniqeness to it (like Anal Cunt or ShitFuckingShit's first album: https://shitfuckingshit.bandcamp.com/al ... -2006-2007). The gorenoise aspect is seen in parts of the first release and heavily in the second, where it is essentially harsh noise wall-grind, or basically goregrind with the gain and level turned up all the way. (https://www.youtube.com/watch?v=NyR9G-IALWA) those two samples/examples lay out the difference in the two and show how it is present in the early tag for Picha.

Gatecreeper are known for having started the hardcore influenced death metal and consistently incorporate it as a secondary genre. I'm not a huge fan of the influences/elements genre tag, but I think adding hardcore as one or the other is appropriate in this case. The hardcore sound is too representative to completely ignore for them.

Death to Honor (pre-Waking the Cadaver) are just listed as "death metal." It's definitely not the slamming brutal stuff they played once they changed their name, but it's still very hardcore influenced, so I'd suggest Death Metal/Hardcore or Death Metal/Deathcore. They don't "slam;" they just play death metal with hardcore influenced chugging.

I love that this band is on here, but why is their genre funk rock? They play Funk Metal, a sub genre of Alternative Metal. They sound far less like Betty Davis and Funkadelic and more like Primus, Precious Death (who I just realized and am surprised are on this site), and The Beyond. I understand that you guys may be wanting to distinctly have this look as a side-project exception, but realistically funk metal is not acceptable on this site, besides some of the funky stuff Faith No More and Mr. Bungle do, so there really isn't harm is changing it. There's also a handful of funk metal genre tags on this site, which are funk/X acceptable metal genre, but it's not a stretch. (https://www.metal-archives.com/search?s ... band_genre)

Normally, I'd probably edit the last post to add this in; but I think this is more important than that.

This one has been bothering me for a while. Why is Hermetica (https://www.metal-archives.com/bands/He ... 9tica/2721) listed as only Thrash Metal? Apart from the first album (https://www.youtube.com/watch?v=-q796hC ... sX4lfd81NY and I'd say even that has more of the thrash/speed metal flavor of early Metallica and some straight speed metal and heavy metal tunes), they are mostly a heavy/speed metal band with some thrash riffs strewn about (https://open.spotify.com/artist/6j6Ld5h0aFgH0VQWQNazS7 "Intérpretes", "Ácido argentino", "Víctimas del vaciamiento").

I think that Cause for Revelation should have hardcore in their genre.
