The Virality Score is a number from 0 to 100 that predicts how shareable your track is across TikTok, Instagram Reels, YouTube Shorts and Spotify. It's calculated by combining outputs from 10 specialized AI models.
The score combines multiple signals: Best Moments hook quality, production characteristics, energy profile, lyrics emotional impact, genre trend alignment and more. It's not just one metric — it's the fusion of 10 independent AI evaluations.
Scores vary by genre, but generally: 0–40 = needs work, 40–70 = solid potential, 70–90 = strong viral candidate, 90+ = exceptional. Scores above 70 have strong chances for Viral Radar playlist consideration.
Yes. The report shows exactly which elements contribute to your score. Use the Best Moments data to understand what hooks work, check your production metrics against chart standards, and iterate on your next version.
Best Moments are the exact 3–15 second sections of your song that are most likely to make someone stop scrolling and engage. You get precise timestamps (e.g. 0:47–0:58) with a confidence score for each moment.
Use them to create TikTok clips, Instagram Reels or YouTube Shorts. Start your video at the exact timestamp where the hook hits. These are the moments that are statistically most likely to trigger shares and saves.
Viral Radar is Songbrain's network of 37 genre-specific Spotify playlists. Tracks with high Virality Scores are automatically reviewed and can be featured — completely free.
Just upload and analyze your song. If your Virality Score is high enough within your genre, your track enters the consideration pool automatically. There is no separate submission process or fee.
There is no catch. Playlist placement is 100% free and based entirely on music quality (your Virality Score). We don't charge for placement, we don't use bots, and we don't violate Spotify's Terms of Service.
Paid playlist services charge $50–$2,000+ and often use fake listeners or bot farms that risk getting your Spotify account flagged. Viral Radar is organic — real playlists, real listeners, zero risk. The only thing that matters is your music.
37 genres including Metalcore, Techno, House, Drum & Bass, Phonk, Trap, Drill, Modern Pop, K-Pop, J-Pop, Afrobeats, Reggaeton, Indie Rock, Shoegaze, Classical, Jazz and many more. See the full list on our Viral Radar page.
Playlists sync regularly. Qualifying songs can appear within hours of analysis. There is no manual review queue — placement is fully automated based on your score.
Absolutely not. You retain 100% ownership of your music and all royalties. Songbrain only analyzes your audio — we never claim rights, distribute, or monetize your tracks.
Audio files are stored temporarily for analysis and automatically deleted after processing. We do not keep permanent copies of your music.
Only you. Your results are private by default. You can choose to opt-in to the leaderboard and Viral Radar playlists, but this is always your choice.
