You have to transfer the FILES to the B2, in the correct (for the B2) directory structure. You can't transfer just the tags. Your tags looks fine; what is the directory structure of the files?
On your USB drive, which must be formatted as FAT32, you can create a top-level "music" directory. Under that you will need a directory that has ONLY directories in it: those should have the "artist" names that you want the B2 to use. Each of the artist directories should have ONLY directories in them: those should have the "album" names that you want the B2 to use. Each of the album directories should have ONLY individual music tracks -- files, not directories.
Thus (using Mac syntax):
/music/artist-subdirs/album-subdirs/track-files
If your files are not already in that structure, that is why I suggested using the mp3tag tag-to-filename action, with the kind of string I provided. That will create the right structure.
Then you could just drag the top-level directory onto the USB and everything below it will copy also.
