Using dark music

Low end needs space

Dark tracks live in the sub and low-mid range. On phone speakers they can vanish, so check the mix on a phone before you publish.

Tension, then release

For true crime or a reveal, run a dark bed under the setup and drop it out entirely at the key line — the silence does the work.

Dark music FAQ

Is this dark music free?

Yes, for personal projects. Every track downloads free in MP3 and WAV, with no account and no attribution. Commercial use — monetized videos, ads, client work, apps and websites — needs a Sonilo Pro or Premium plan.

Can I use it in a monetized YouTube video?

A monetized channel counts as commercial use, so it needs Pro or Premium. Sonilo does not register library tracks with YouTube Content ID.

Do I need to credit Sonilo?

No. None of the library tracks require attribution, on any plan.

What if I can’t find the right dark track?

Describe the one you need — instruments, tempo, mood, length — and generate it with Sonilo’s text-to-music. New accounts get free credits; custom tracks follow your plan’s license.

License
