Don’t worry, Steve… Paul (whom I fully respect) and I (and others) often have this friendly debate 
 .
In case you do turn out to be interested in tagging software - and you really should (if I may be so bold): essential in getting the most from Roon - Paul’s comparison is in some places inaccurate and misleading in ways which have been discussed here often.
But do look at both packages (again) and make up your own mind. Yate is on version 7 now and is updated often. SongKong also works well, to be sure, and may do the job. Good luck!
