Did this change recently?
After mucking around with my coverart options this morning, I notice that [bios], [lyrics], and [image file], if present in the files' tags are not removed during an 'update tags from library' when "save in tags (when possible)" is unticked.
This was definately not the case 19 days ago when I did the tests above.
I see that in the file type info window:
[bios] falls under "COMM (MusicMatch_Bio): i am a test bios"
and when "saved in file" it appears down the bottom of the window with all the proprietry MC tags, and when not saved in file, it moves up the list to be amongst the non-proprietry fields. MC doesn't remove it.
same applies for [lyrics], saved in a USLT tag, not removed
and for [image file], saved in an APIC tag, also, not removed.
Unticking the save in tags (when possible) for other proprietry fields, I tested with [rating] and a cutom 'string type' field, does remove them in an 'update tags from library' sweep.
Now I'm confused.
Are [bios], [lyrics], and [image file] now considered safe tags, and so, if MC is asked not to save them in the file, it won't, and at the same time, it will never remove existing tags of this kind unless by way of the 'remove tags' tool?
If I go that right, are there any other fields also protected this way?
and if I got that wrong, would someone please try and explain what goes on for me, one last time?
thanks:)
