Media share

[Atalantia]

Hello People,
I activated Media share on one of my computers because I want to have the playlists and music from this computer on other computers in my LAN. It works so far except that of all things, the tunes I listen the most currently don't play.
I compared the files with mdls but I cant either find a DRM protection nor anything else suspicious.
One of those not working looks like that:

/Music/Music/Media.localized/Senri\ Kawaguchi/organizer/01\ FLY.m4a
