I agree with you that there wont (or shouldnt) be a one size fits all AI solution for millions of different pieces of music. The same reason why mastering audio is considered an art form as much as a science applies here-- it involves deep understanding of intent which goes far beyond simply analyzing waveforms Theres also a lesson to be learned about using sorts of style transfer to add dimensionality to past artwork which is that maybe the artist would have deliberately omitted these new dimensions even if they were made available at the time, so the new dimensiona effectively change the original intent, and shouls may be considered an entirely new artwork with somewhat different authorship and different message altogether
