Chikoi The Maid is a special one for me. I think he's the most popular Maidcore composer today, and his tracks are something else. He combines his own style with post-rock and the result is something that you can listen to in almost any situation.
My favourite song by him is "Outland". Click the song name to listen in the player above. There's also "The Past", it's one of the relatively new ones.

Medoi the maid is another Maidcore composer that I like. His music is very emotional and lonely, but sometimes it's "all-out", good for workouts.
One of the great songs is "Violent Purple". There's also "Надежда Значит Беда", which is a collab track with the band "Исчезнувшие".

Garoad. This guy is special. He wrote the soundtrack for the game VA-11 HALL-A (the game that this whole site was inspired by).
It's hard to choose a favourite, but I think for me it's "Digital Drive". Besides that, there are a bunch of good tracks, for example "Karmotrine Dream".

Kichi the Maid is like Chikoi, but different in his own way. Maidcore composer, popular enough to collab with Chikoi himself.
There's a bunch of good stuff, here you can listen to, for example, "Ataraxis", which is a collab with Chikoi. There's also a good instrumental cover of the song called "Аутоагрессия" (Autoaggression) by "Три дня Дождя" (Three Days of Rain). Here it is: "Аутоагрессия".

"Singles only"
Zetsubou-P is mostly a vocaloid composer and every time it's Hatsune Miku. His main genre is metal.
I really like his songs, his guitar and Miku is just so well done, listen to the "Within My Hands" for example. He also has a collab with Kichi: "Digital Resurrection". There's also something without Miku (well, a version of it): "Tainted Love".

"Shinda"
Yansanes is a hidden gem really. Another one metal Miku composer.
My favourite song by him is "Baroque Doll". There's also a Miku version, but this one is better IMHO. Second favorite is a collab with Zetsubou-P: "Brain Cleaner".
