Composition tag

[alfreddo12]

I am about to refine the tagging of the classical part of my collection by adding a composition tag. As we are on Linux (Ubuntu 12.04 /13.10 plus Vortexbox with MinimServer) CDs had been ripped using dbpoweramp (wine) and downloads have tagged using puddletag (or, in earlier days, mp3tag (wine)).

Surprisingly, MinimServer does not recognize the composition tag if I add it in puddletag even though the tag information is written into the file, according to verifications with mp3tag and the tag-editor of dbpoweramp (displayed as "composition", not "Composition"), on a friend's Notebook. Also, if I add the composition tag using mp3tag ("COMPOSITION") or the tag-editor of dbpoweramp ("Composition"), Minimserver recognizes and displays it immediately after a restart.

I have already tried to define the composition tag as "Composition" instead of "composition" in puddletag, without any effect.

I wonder whether others have the same issue and whether it is down to puddletag, Minimserver or else.
