Hi, i'm adding custom tags to my classical collection to use via excellent Erland's CustomBrowse plugins:
+ WORK
+ MOVEMENT
+ ENSEMBLE
+ LABEL

That's works perfectly with FLAC files but not when i add custom tags on M4a(AAC)files. Tags are correctly read in MP3tag and Foobar but not recognized via Squeezecenter (or CustomScan).
M4a "regular" tags are read.

Any experience welcome.
