Twonky Forum

Hi,

are there any known issues handling genre tags in m4a files?

I have a bunch of m4a files I copied over from iTunes (downloaded from iTunes Music Store as well as ripped from CDs) and Twonky shows the genre as 'Unknown' for most of them. All my MP3s show correct genre so the problem affects only m4a files.

Twonky seems to parse the problematic files fine since it doesn't complain about unknown tags.

AtomicParsley shows that the genre as
Atom "gnre" contains: Metal

Some files are recognised correctly and they seem to have a slightly different genre tag:

AtomicParsley shows that the genre as
Atom "©gen" contains: Holiday

"Genre comes on 2 atoms - standard genres are on gnre; custom genres are on ©gen; only 1 is permitted at a time."

(dupliate post to answer someone else with same problem)
there seems to be a few problems with m4a format. I'm wanting a solution to:
- doesn't use GENRE
- doesn't use ALBUM ARTIST

I certainly hope an upcoming release will resolve this.
