Sound Virality
Built at Built with Opus 4.6: a Claude Code hackathon · Feb 10, 2026
A single viral moment on TikTok or Spotify can generate millions in streaming revenue, sync licensing deals, and touring demand — making the ability to predict a track's resonance before release one of the highest-leverage decisions in the music business. Artists and music professionals have no scalable way to pressure-test a track's potential before release. Feedback today is gut-driven, unstructured, and trapped in small circles — making it nearly impossible to benchmark a song against its intended context. SoundCheck is a music virality rater where artists upload tracks, select a target context (TikTok, Spotify, Radio, or Sync), and submit them for community evaluation. Raters score each track across four context-specific dimensions -- dimensions that change per context because what makes a song "good" depends on where it's going and what stage it’s at. A credit system keeps participation reciprocal: rating others earns credits to submit your own tracks.
