At the current rate of progress maybe it'll be months. I did a song for my company just to have fun around an event and the quality of the song was astounding, better than this one I think also using v3. I didn't even write the lyrics, I just described what I want in the prompt. Also I used one of poems I wrote as a teenager (not a lot of them) to create a song... the AI would notice the emphasis in the feelings of the lyrics, exactly in the same way I felt them, so it made pauses and chorus accordingly.
