#623 XLD CLI: GENRE, ARTIST, COMMENT and OTHER TAGS not added

[scrutinizer]

Hello,
I'm using the CLI version of XLD to split tracks according to a cue sheet. The spirce is AAC and the target is AAC too. My sheet looks like this:

FILE "Great Masters Of The Keyboard, Paderewski, Pachmann, DeFalla, Granados, Scharwenka.m4a"
TITLE "Great Masters Of The Keyboard, Paderewski, Pachmann, DeFalla, Granados, Scharwenka" M4A  
   TRACK 01 AUDIO
     TITLE "Minuet Op. 14 No. 1 in G Major"
     INDEX 01 00:00
     REM GENRE Classical
     COMPOSER "Ignacy Jan Paderewski"
     PERFORMER "Ignacy Jan Paderewski"
     REM COMMENT "piano roll recording; Welte-Mignon"
   TRACK 02 AUDIO
   ...

It splits successfully, but except for the title, no other tags show up in the resulting files. I verified this with both ffprobe and exiftool. I need my metdata to appear as shown above. Why is this happening or, if it's by design, would the developer mind adding the capacity to embed all metadata tags.
