Bryston DB, unless you click on the name of one of your drives your navigating by the bryston DB. As soon as you stop seeing names of usb/network drives and before you see TIDAL/favourites/playlists all those options come from the Bryson DB. Bryston DB in the current stable form is derived from data collected by MPD. Bryston DB in the current testing release first takes what mpd has available, creates statistics based on what it See's and attempts to fill in the blanks. If artist, album, track or track number is missing it'll attempt to use parts of the file path to fill these in. If albumartist or genre are missing, it will attempt to match existing piecse (artist, album, track name, track number) to entries in musicbrainz to find matches. If genre is not found, it'll grab genres for the first ten albums and use the one that most commonly appears. If the albumartist value can't be confirmed or found it will attempt to use statistics collected earlier to figure out which foldername should be used. I believe that's what I have completed so far, it's been super hectic last couple of months. Next it's my intention to build an interface allowing users to change these values and fill in ones that are still missing. Keep in mind these values aren't generated unless the bdp/mpd can't find them. These bdp generated values aren't applied to your music files or even files stored on your drive, but a database file stored in user space (bdp's internal storage). I hope this clears things up, as usual constructive feedback is all ways welcome.
