100-word summary
Google just released Lyria 3, its latest music generation model, into public preview. Developers can now spin up tracks nearly three minutes long through the Gemini API, a leap from the 30-second clips most AI music tools offer. You can feed it a video and get synchronized background music, or hand it an image to set the mood and genre. The system handles multilingual vocals, lets you specify tempo, and time-aligns lyrics to the beat. Every track gets watermarked with SynthID so listeners know it's AI-generated. Google is betting creators will license AI tracks for YouTube Shorts instead of wrestling with royalty-free music libraries.
