Google has expanded Spaces, the build-your-own-instrument area of Flow Music, so a user can generate a song, cover, extend or replace parts of it, split stems, write lyrics and make artwork and video without leaving one workspace.
Flow Music grew out of Riffusion, later ProducerAI, which Google bought in February and rebranded. It runs on DeepMind's Lyria 3 Pro for music, with Gemini, Veo and Nano Banana handling text, video and images, and it stamps output with the SynthID watermark.
The update puts Google closer to Suno and Udio's editing suites. Like them it faces litigation: independent musicians sued in March, saying Lyria 3 learned from YouTube recordings without permission, while Google says its terms allow that use.
