How to Swap in Your Own Tracks

Find DRM-free music from sources like:
- Kevin MacLeod / incompetech.com — CC-BY (requires attribution)
- Pixabay Music — mostly CC0
- Free Music Archive — various licenses
- Musopen — public domain classical
Drop your file in this directory with the same name (e.g. combat.mp3). The file can be any audio format the browser supports (WAV, MP3, OGG).

Update manifest.json if you change filenames or add new moods:

{
  "mood": "combat",
  "file": "combat.mp3",
  "title": "Your Track Title",
  "license": "CC-BY Kevin MacLeod"
}

No code changes needed — the frontend reads the manifest dynamically.

License Notes
