voca/utau producer favorites

i might make a general music favorite but i really want to talk about some producers i like honestly lol x_x heres infodump central and spotify playlists of 10 songs of my choosing yayyy

ishifuro!
also known as asahi... he used mostly sf-a2 miki and ia and did a lot of fun duos with ia + one. he has moved onto the rock band necry talkie as a guitarist and songwriter since he talked about losing motivation on making more vocaloid songs...but he still makes vocaloid music every now and then, like his newest released voca song was about a year ago?
necry talkie also has made two albums (memories/2) as covers for a lot of asahi-san's old vocaloid songs and its a lot of fun with mossa's vocals i think! check them out too! STREAM NECRY TALKIE

iyowa!
his songs make me go CRAZY they have a very chaotic pace to them. recently i mostly see him use the musical isotope series, specifically KAFU... most of his songs also have a PV to go with, so make sure to watch them too! he draws them all himself! i also know he has a line sticker set for his characters known as "iyowa girls"... theyre very fun. he is also like the only producer on this list probably that still regularly uses vocaloid LoL

siinamota!
or powapowaP/highcolor_sunz! my favorite ;_; he mainly used miku for everything but ive heard a few rin and gumi songs from him as well. some of my favorite versions of his songs are his own vocals, pocket sized acoustica is a good one...
a lot of his songs are sort of "lost" since many of his work in progresses or unpublished works were exclusively put in discs that were sold on special events... but you might have already known his song Strobe Light! (or Young Girl A that was apparently a tiktok trend?)

n-buna!
probably more well known for being part of yorushika at this point... his old vocaloid songs have a special place in my heart though. i would guess if you're a sekai player then you probably know him for tale of the deep-sea lily... otherwise his more well known songs are toumei elegy and dawn and firefly!
like asahi-san he doesnt make vocaloid music anymore and more prefers to work with a vocalist... suis and n-buna are a very fun duo though, they sometimes talk in her radio show music freaks (you can find a subtitled version here :3)

x0o0x_!
they dont actually have most of their utau versions on spotify so its mostly their own singing in this playlist, but they do make a utau version for every song they upload!
umm i know to en viewers they seem to be viewed as a "cult" kind of thing? its really nothing like that lol their work mostly themes around urban legends so they all have a bit of a story behind them. theyve also collabed with x髥莏 which i think is so sick

maybe ill add more later when its not 5 am </3
