VAULTKID (NEEDS REPAIR)
A smaller sub-label for miscellaneous exclusives and deleted Sonic4 Test Records releases. You can find music

by Sonic4, James Woz, Stomach Acid, Local Radar, HappyEpicBoi, Tewi Inaba, and more in our catalog.

AYTRACKER (UNFINISHED, NEEDS OVERHAUL)
A work-in-progress collection of outtakes, early versions, and other unreleased media from throughout Sonic4's discography. Features in other albums, gallery of artwork, and other miscellaneous stuff can also be found here.

THE PROTAGONIST (NEEDS REPAIR)
An outdated legacy microsite containing everything about the classic era of The Protagonist. You can find more information about each release, what went into making them, and other exclsuive content like gallery and trivia.

YUKARI'S ALBUM REVIEWS (LOST, NEEDS TO BE REMADE)
A borderline useless microsite for Yukari to review every Sonic4 Test Records release. Bringing it back would give us a solid reason to host more listening parties and revisit our legendary past, so that's why I'm going to do it.

STOMACH ACID MICROSITE (LOST, NEEDS TO BE REMADE)
Despite not being a real member of Sonic4 Test Records, Stomach Acid was a real O.G. who is loved by many and deserves to have a microsite that shows his albums, paintings, and other creations that make him proud.

SONIC4 365 (LOST, NEEDS TO BE REMADE)
For the entirety of 2026, I'm planning to make one song every day with a diary entry attached to it. It's an insanely difficult challenge with a microsite that's sadly lost, so having to remaking it from the ground up will be difficult too.
