Engine OS: How To Add Multiple Genres To ID3 Tags?

Hi! I have a Denon DJ Prime 4, and I"m on the latest version of Engine OS (5.0.1). I’d like to be able to have “Genre” tags that work properly. First of all, what version of ID3 tags does Engine OS read? Second, what format works to separate genre tags? Is it a comma, semi colon, or something else entirely?

Thanks!

I did an experiment. I tried using:

  • \\
  • ;
  • ,

I used these to separate multiple genres on some FLAC files. None of them seemed to result in actually separate tags, but monolithic single genre composites. What is everyone else doing to organize their music so the sorting works properly?
