Shoutout to @grimreapersprint for actually exploring/explaining each of these in our discord! Here are her findings:
Dirtstep - technically yes, and it sounds exactly like what you would expect
Grassgaze - I found one song and it’s strangely ominous
Leprechrust - No, which honestly surprises me
Flowerviolence - real and sounds like crap
Shroom N’ Bass- This is just Hardbass with extra steps
Moss Rock - sounds kind of like older bluegrass listened to from a distant cavern except extremely loud
Shiny Rock - Sounds like if you gave a Nirvana cover band a fistful of molly and shrooms
Garden Core - Sufjan Stevens on a near-lethal dose of Xanax
Cavern Core - Sounds like cookie monster started a garage band in an abandoned aircraft hanger
Treewave - The one song I found sounds like getting a severe concussion in the middle of a house track
Birdsong - gentle chirping backed by a hurdy-gurdy the size of a volkswagen beetle
Whistle Choir - Unable to disambiguate
Subterranean Folk - yes if you count underground folk, which absolutely sounds like gnome music
Dark Underground - this sounds what executive dysfunction feels like
Deep Underground - Hardbass with fewer steps OR chugging an entire bottle of cough syrup and then trying to pull off a jazz drum solo while someone plays a keytar in the background
Earth Metal - Just because you CAN daisy-chain three distortion pedals together doesn’t mean that you SHOULD.
Star Metal - This is actually kind of a complicated subject and beyond the scope of this review
Rootbop - no, which is a shame
Meadowpunk - found one song about bitching about condos
Solarpunk - Noting the above exception, most “-punk” musics are different genres with songs about/atmospherically designed to fit the aesthetic of what is more of a social/visual aesthetic
Moonpunk - See above, but if it existed it would sound like rockabilly
Stump Stomp -No, which is kind of a shame, really
Woodwind - literally a category of instruments
