mAirList can only update ID3v2 tags (in MP3 files) so far, no other file types.
Actually I consider dropping the file tag writing altogether, for two reasons:
Most of the time it doesn’t work anyway, because the file is locked on disk while loaded into mAirList’s players or Cue Editor.
Only a small selection of fields is written back to the file tag anyway, not all fields from the Attributes tab! That’s not quite what the user expects - and (with the time I have) it’s impossible to write a full-featured file tag writer that is as powerful as e.g. mp3tag. I don’t think that’s a key feature for a radio automation software anyway.
You’re right Torben, at least I’ve got an escape. Still in favour of the MP3 tag though, MMD’s might get seperated from the MP3 file. Anyway, there are more important things in life!
