So you use Mp3tag version 2.46.
I assume you want to tag your files with Tag version ID3v2.3 with UTF-16 character encoding.
Set Mp3tag to use this as your default tagging format.
Your tag fields are named ARTIST and TITLE.
From what should the content of ARTIST removed? From the filename?

Supposing the tag fields in the music file are properly filled and you want to set the filename to a new value, you can use Mp3tag/Convert/Tag-Filename with the format string %TITLE%.
This will set the filename to the content of the TITLE tag field.
You can press the Preview button to have a look at the result before physically applying the change to the file.

Supposing that the tag fields ARTIST and TITLE are empty or do contain erasable informations, and the filename contains the information for setting the tag fields ARTIST and TITLE, then you can use Mp3tag/Convert/Filename-Tag.
With a given filename of "artist - title.mp3", where "artist" stands for the textual information about the artist and "title" stands for the textual information about the title, both parts separated by a literal string of ' - ', which is unique to the both informations parts, then you can use the following format string (or mask) to fill the tag fields automatically with the related content from the filename:
%ARTIST% - %TITLE%

In the prviously message there was an error with the format string.
I have written erroneously:
%ARTIST%' - '%TITLE%
In this case Mp3tag treats the single apostroph literally as a character, not as a string delimiter!
So the correct format string should be:
%ARTIST% - %TITLE%
