I would prefer option 2 as that will show if this field is populated even though I am not actively looking for it (if I understand it correctly).
I tried to add this now, but I think it is too advanced for me... Do you know how I could add this field?
I see some flac files include the Copyright information as well. This is also interpreted as Comment in some programs. (Tried to upload a screenshot of this as well, without luck...)
To add a new field to your file (column) list, you have to
a) Right click on a existing column header (like "Album")
b) Choose the context menu item "Costumize columns..."
c) Click on the "New" Button
d) Enter a name for your new column, like Description
e) As Value type %DESCRIPTION%
f) As Field type %DESCRIPTION%
It should look like this:
Then press the OK-Button.
You can repeat this steps for every tag you see in ALT + T, also for COPYRIGHT
