Not much, because not many tracks are so affected. One example, the artist “JerryGarcia/David Grisman” shows in Tracks for the album “Shady Grove”, however, on my NAS the artist is given a “David Grisman”, the album is listed as Shady Grove, and the songs are listed such as “01 Jerry Garcia - Shady Grove.flac”. The NAS did not put the “/” there, Roon did.
Another riddle. My NAS has artist “Annie Moses Band” with two albums titled “Always Morning Somewhere” and “Eden”. Roon Tracks lists the album “Eden” under artist “Annie Moses” which is listed on Tracks in white and neither the artist “Annie Moses” nor the album “Eden” appear under Roon Artists. In Roon Tracks “Annie Moses” is alphabetized under “Annie” indicating that Roon sees it as a band rather than an artist name. Right after that in tracks is the artist “Annie Moses Band” listed in blue and the other album “Always Morning Somewhere”. These show up in the Artists list and are playable. Eden is not. The NAS shows them identically listed in format
Annie Moses Band > Always Morning Somewhere
