You get an original Father's Day song with vocals as an audio file, with lyrics written from your memories or the lyrics you give. The voice sings the name you give.\n\nChatGPT tells you what the song needs and creates it in your MegaScenes account when you ask. The song plays in the chat and stays in your library.\n\nGive only the name and the details you want sung: no address or contact details are needed.\n\nTo play at a Father's Day barbecue, send in the family chat or add to a video for him.\n\nLimitations: original songs; it does not imitate a real singer's voice or copy an existing song or artist. 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.",
