AI vocals vs hiring a singer vs a new song from a prompt

How AI adds vocals to your instrumental
Producers use it to hear a topline over a beat before booking a singer, songwriters use it to turn lyrics and a backing track into a demo, and creators use it as an AI singer for their song when they have an instrumental but no vocalist. Because you can upload your own file, the beat does not have to come from RaoMusic.
The AI writes a vocal melody that follows the key, tempo and sections of your instrumental, then sings your lyrics over it. The result is a new render of the whole track, so expect the arrangement to stay close to your beat rather than sample-identical.
For the best result, upload a clean instrumental with no existing vocals, mark sections with [Verse] and [Chorus] so the vocal lines up with the structure, and keep the lyric length realistic for the length of the track. If a take doesn't fit, adjust the style or lyrics and generate again.
