Extend Song lets AI keep writing your song. Upload the audio file to extend (mp3 or wav, up to 8 minutes), fill in the title and desired style, and AI composes new sections from the end of the track, automatically merged with the original into one full song. Lyrics are optional: write your own for the extended part, or leave blank and AI writes them. Great for growing a short melody into a complete piece, adding a second verse and chorus to an existing song, or lengthening background music. Generation takes about 1-10 minutes; you get download links for the full merged song and the extended section. Please upload only music you created or are licensed to use. Audio output format: MP3.
