ミュージシャンがリリース前に楽曲の所有権を証明する方法

You produced the beat in January. Sent it to a vocalist in February. In March, a track with your exact progression drops on a different artist's EP — no credit, no payment, no acknowledgment. Your beat. Their name.

This story plays out thousands of times a year. And the musicians who come out ahead are the ones who can prove timing.

Why Sending Beats Is the Highest-Risk Moment

The moment a beat or demo leaves your hard drive, you lose control. WhatsApp doesn't keep chain-of-custody records. Email timestamps can be contested. Collaboration platforms track uploads, not creation dates.

The window between creation and release is when your work is most vulnerable. A timestamp created at the moment of creation — before the file is shared with anyone — closes this window.

What to Timestamp and When

Every beat, stem, and master as soon as it's bounced. Lyric sheets before they're sent to collaborators. Project files at key milestones (even rough drafts). Demo recordings before they go to labels or A&R.

The habit takes seconds. The protection is permanent. And the cost per proof is less than a coffee.

How It Works in a Dispute

If your beat appears on someone else's record, your blockchain timestamp shows that you possessed the exact file — byte for byte — at a specific date and time. The other party would need to produce evidence of an earlier creation date. If they can't, the timeline speaks for itself.

This isn't a silver bullet for every legal scenario. But it's the single strongest piece of evidence a musician can create proactively, and it's available to every producer regardless of budget or label backing.
