Grooving to Your Own Beat: How to Dive Into Custom Songs in Project SEKAI

If you have spent any time scrolling through rhythm game TikToks or YouTube shorts, you have probably stumbled across jaw-dropping Project SEKAI: Colorful Stage! (PJSK) clips featuring wild, fan-made charts of songs that aren’t actually in the official game. From underground Vocaloid tracks to meme hits, seeing custom charts makes you wonder: How do people play those? Can I get custom songs in Project SEKAI?

While the official mobile app doesn’t have an in-game “import song” button, the community has found awesome ways to experience fan-made charts and custom audio. Let’s break down how custom songs work, how players enjoy them, and how you can get started.

1. Understanding How Custom Songs Work

First things first: you cannot directly mod custom MP3s or fan-made note charts into the official, downloaded Project SEKAI app from the App Store or Google Play. Trying to tamper with the official app files usually results in game crashes, errors, or risk to your account.
