ViralMint's music tool calls Google's Lyria 3 Pro via OpenRouter — the model that drives YouTube's own creator music tools. You get the same audio quality, the same instrumental focus, and no vocals (deliberately, since most creators want backing tracks they can talk over).
12 presets cover the full spectrum: Lo-fi Chill (study-tube), Cinematic (vlog establishing shots), Upbeat Electronic (TikTok hooks), Ambient (meditation), Corporate (explainer videos), Jazz, Hip-Hop / Trap, Classical, EDM, Acoustic, R&B, Rock. Layer a Mood (Chill / Hype / Cinematic / Cozy) on top and you have ~50 distinct vibes without writing a prompt.
Suno is $10/month for ~500 songs but watermarks free outputs. Soundraw is $16.99/month with a 50-track download cap. ViralMint charges $0.15 per generation — flat-rate, no monthly minimum, no watermark, no track caps. Generate 5 takes for under a dollar.
In the free ViralMint desktop app, open the Music tool. It defaults to Lo-fi Chill — the fastest way to hear what it sounds like.
Toggle Custom Prompt for free-text input ('warm lofi beat with vinyl crackle, 90 bpm, instrumental') or stick with one of the 12 presets. Add a Mood (Chill / Hype / Cinematic / Cozy) to color the output.
Slider runs 15s to 4 minutes in 15-second steps. Lyria is flat-priced so duration doesn't change cost — pick what your video needs.
Click Generate ($0.15). The track streams over 30–90 seconds in the cloud; once complete the audio plays in the app and a Download mp3 button appears. The track also lands in your Library for re-download within 30 days.

Almost every creator who generates AI music wants a backing track they can talk over — vocals fight the voiceover and add IP risk. Lyria 3 Pro's prompt template explicitly asks for instrumental output (the genre presets all end with 'no vocals'). If you specifically want a vocal track, the AI Voice generator handles narration; the AI Music tool intentionally stays out of the singing-AI space.
Yes. Google's Lyria license permits commercial use of the generated audio with no royalties owed. The track you download is yours to monetize on YouTube, TikTok, ads, podcasts — anywhere.
Lyria 3 Pro is exposed via OpenRouter's chat-completions endpoint as an audio stream — the model takes a real chunk of compute time to generate each track end-to-end. ViralMint runs it on a worker Lambda with a 5-minute budget so even longer tracks complete reliably. The portal shows a live progress timer so you know where you are.
Yes — every generation uses a fresh seed, so re-generating with the same prompt gives a different take. Most creators generate 3–5 variations of a prompt, keep the best, and discard the rest. At $0.15 each, that's well under a dollar to find the right vibe.
ViralMint routes through OpenRouter, which gives us a single switch to swap in any other AI music model if Lyria pricing or availability changes. The desktop app's Smart Video pipeline also accepts your own uploaded music tracks as a fallback — see the Music Library page in the portal.
The AI Music Generator ships inside the free ViralMint desktop app — no subscription, no watermark, no per-minute cap. Download once, use on as many videos as you want.
