Separate track for lead vocals

AI song generation services seem to always record the vocals to the same track as the music. As a vocalist using Songer.co exclusively to produce demos of my original songs, this is frustrating because removing those vocals leads to phasing and makes the track unusable for me to be able to perform my own songs myself. Recording the vocals to a separate track than the music/backup vocals would allow Songer.co to do what I have not been able to find anywhere else. You could offer the completed demo, but you could also offer a karaoke/performance track for download simply by removing the vocal track.

I know I would happily spend extra credits to be able to download a clean track with no lead vocals. I want so badly to perform the songs I have created on Songer.co and this would give me that ability.
