What changed
Google began rolling out Lyria 3 in beta so Gemini users could create 30-second songs from text, photos, or videos with generated lyrics, vocals, tempo controls, and cover art. Generated tracks carried SynthID watermarks, and the model also began expanding through YouTube Dream Track.
Why it matters
Music generation became an everyday multimodal feature rather than a separate specialist tool, letting images and video directly seed short custom soundtracks.
What to do
Use it for licensed social prototypes, specify genre, mood, vocals, and tempo, and retain the SynthID-marked output and prompt as provenance.
Caveat
The beta produced only short tracks, Google framed them as expressive clips rather than finished music, and users still need to check rights, likeness, and style-imitation concerns.
