Question about Group tag and track renumbering

If you are using track renumbering, the track numbers sent to the control point won't match those in the booklet because they use a single increasing sequence for the complete album. If you use displayFormat to send track numbering information, the numbers will match the booklet because the $tracknumber and $discnumber entries in the format string are replaced by the original tagged values.

Fine, this means I can show or hide the original numbers via displayFormat and don't even have to retag my music files when I change my mind.

You can use Group.displayFormat if you want the group entry to include a track number. The track numbers for the tracks within the group should be displayed correctly by most control points.

BubbleUPnP (Android) shows the track numbers sent by MinimServer when using "Show metadata" from the context menu on the track, and it shows the track count with "Show metadata" on the group. UPnPlay (Android) shows the track number for each track (below the track title), and for a group it shows both the count of tracks in the group and the first track number for the group below the group title. The Naim app ignores the track numbers and does its own numbering always starting at 01 in each group.

When doing so it is best not to set the DISCNUMBER tag for single-discs albums, because the disc number is then only shown for tracks on multi-disc albums.

Thangs a lot for your explanations.
