JASRAC: AI-autonomous lyrics or music not managed, filing must say so

It reads JASRAC's official guideline and translates the key rule into practical terms: if AI autonomously generates the lyrics or the music from simple prompts, that part is not a work JASRAC will manage. The guideline's table sets out management rates that differ depending on whether only the music, both lyrics and music, or only the lyrics are used, and on which side was AI-generated. The person filing must guarantee the work includes human creative contribution, and JASRAC can request supporting materials if it has doubts about a filing. Because the guideline does not specify what those materials should look like, the author recommends keeping dated records of what was left to AI and what the person did. To make that concrete, the author added three JASRAC filing checks to a browser-based tool called AI Release Check (version 0.3.0) and showed sample output for a song where the lyrics were written by a person and the music was AI-generated. The tool also produces a production record that can be copied and kept locally. The page is not affiliated with JASRAC, the line between a simple instruction and human creative contribution is not machine-decidable, and rules can change, so each check item carries the date it was verified.
