Citadel sits in our edm hub as a full-length instrumental-friendly piece (~4 min). Zombie Hyperdrive released it under CC0 / public domain; Soundex only catalogs it — we do not re-license or watermark the audio.

Longer than a sting, shorter than a film cue: at ~4 minutes you can cover a scene without an obvious loop point. Mark the waveform in your editor; do not assume the Archive file has perfect silence at 0:00.
