You won’t get it from a Nam rip because it doesn’t generate any file tags.
It was a long process for me to put all the correct tags in al of my Naim ripped files and I expect I will continue to find untagged files in my music collection. It was worth the effort, both for getting the correct tags, but mostly for the superior musical quality of files streamed from a NAS via Asset or Minimserver, compared to streaming them through the HDX-SSD.
