I don't know how to add this question into this issue below.
So I'm going to ask it here & display the issue and the solution below.
First, when I want to break up a line to begin the info on the following line (called a Line Break)
I use the Windows "SHIFT + ENTER" keys in Word, etc. I don't remember if I've done that in MP3Tag.
It's logical to me that Comments should always be multi-line.
So if I use the instructions below will this become the default then for all future COMMENT fields when I use MP3Tag. I hope so (that would save a lot of time). Please let me know either way.
I can't imagine why you wouldn't have COMMENT(s) as multi-line.
Right-click in the grey area of the tag panel and select "Adapt ..." in the menu or use Tools>Options>Tag-Panel.
There select the entry for Comment and click the Edit button.
In the drop-down list for "Size" select "multiline".
