I'm interested in Cerio's observation that the quality of the source file makes a difference. Like Gordon, I had not considered this.

Although I have only fed WAV files into Song Master Pro, the source of those WAV files might be from recording something of lesser quality, such as a YouTube video. I assume such a file is already compressed considerably. I plan to run a comparison of the same song recorded from Apple Music (high quality) and YouTube. And maybe a file ripped from a CD.
