Yes — and you don't have to lose the song. The trick is separating the composition from the performance.
1. Cover is your tool. Take the old song and Cover it with the same lyrics. Cover re-performs everything, and the current voice models are dramatically better than the old ones. Same song, new singer.
2. Keep the melody with a reference. If the old melody is the part you love, Cover with a prompt like same melody and phrasing, new warm female vocal — plus keep style-influence low so it stays faithful instead of reimagining.
3. For total control: stems + re-sing. ... > Get Stems on the old song, keep the instrumental stems, mute the old vocal stem, and generate a fresh vocal-only Cover of the lyrics. Drop the new vocal onto the old instrumental in a DAW. Best of both worlds — the original band, a brand-new singer.
4. Save the new voice. Once you get a voice you love, note the exact Style wording that produced it (or save as a voice/persona if available). Future songs stay consistent.
Don't regenerate the song from scratch hoping for a better voice — you'll lose the arrangement you liked. Cover preserves; regenerate replaces.
