The track plays in the chat and stays in your library.\n\nFor video soundtracks, game loops, podcast beds and study music.\n\nLimitations: new instrumental tracks from a description; it does not copy an existing song or artist, or edit audio you attach. Making a file needs a signed-in MegaScenes account and runs in it; nothing is made until you confirm. Not for sexual or adult content or for real people's likeness. Files are made by generative models and saved in your MegaScenes library.",
