Ok, so some more details about round 10.
I'm breaking up musical styles into tiers of challenge, based on video game-esque difficulty levels. This is to provide a slight incentive and reward for picking more challenging genres, though you should be increasingly wary of them. To make it less subjective and easier to arbitrate, the basic litmus test for eligibility is going to be whether the topline primary bolded genre listing on Rate Your Music matches one of the genres. It can be a co-primary with another genre, but not be a non-bolded secondary genre. Hopefully this will be intuitive even for those who don't use RYM often, but if not I can link to examples. I may have to step in and make judgment calls if the songs seem to be outliers in regards to the style.
I will also accept less common styles not listed and potentially assign difficulty points, though if I'm completely unfamiliar with the style the default assumption will be that it's an easy mode genre. I will reject genres that I know too much about, the point is to expand my horizons some in this round.
Easy Mode - country ('79 and earlier only), experimental rock, indie pop/rock/folk, J/K-pop/rock/metal, neo-psychedelia, pop punk, post-rock
*no bonus points for picking these genres
*I don't think I actually dislike these styles, I certainly have artists/albums/songs I like in them, and some have already scored very well in this roulette. I just have slightly negative feelings about them for sometimes arbitrary reasons likely based on poor earlier exposures to particular niches of them.
Medium Mode - metalcore (90s only), Britpop, emo, experimental, math rock, mathcore, hardcore punk (no Swedish artists), opera, hip-hop (2010-present only), show tunes
*automatic + 0.25 to your score for the round for selecting one of these
Hard Mode - avant-garde x, death industrial, free improvisation, free jazz, hyperpop, industrial (industrial rock/metal and electro-industrial don't count), noise rock, post-hardcore
*automatic + 0.5 to your score for the round for selecting one of these
Nightmare Mode - harsh noise, power electronics
*automatic + 0.75 to your score for the round for selecting one of these
---
*I would be cautious about hard and nightmare modes in particular, the vast majority of what I've heard in them would not score well, hence the difficulty bonus.
*Also, feel free to ask about particular styles and I can give a quick synopsis of what I struggle with about them (it may very well be something I've already written about in various writeups).
I'm still working on early impressions for round 9, those should come in the near future.
