The song plays in the chat and stays in your library.\n\nFor birthdays, jingles, gifts and songwriting sketches.\n\nLimitations: original songs; it does not imitate a real singer's voice or copy an existing song. 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.",
