I currently have Nova Fidelity X12 which I use as a NAS drive and access it through the SONOS app to play music through the SONOS. Like the B2, the X12 has a web UI which I use to edit CD information like rename tracks etc. The problem I have is that the X12 uses the mp3 file name as the track name whereas SONOS use the "title" metadata tag. This means that SONOS is not picking up the changes to the track name because the tag is not changed.
What I would like to know is where does the B2 get it's data from. Is it using file and folder names, or is it looking at the file metadata? Or some other mechanism? If I change a track name through the B2 UI what is being changed, the file name, the metadata or something else?
