Thanks ! Had never heard of ReVox until now… Anyway you mention " there is a possibility, that you will have to delete\re-upload those music files to VOX Cloud once again in the worst scenario"
There is no functionality to delete music files in VOX Cloud so I am not sure how that would work.
If I am going to have split albums with no ability to delete albums, I will wait until there is a new version of an uploader or you can confirm how I can delete.
