I know mp3tag can (almost) do everything - how about this ?
Johann Strauss wrote 479 pieces of music, I have all as mp3-filess, some multiple by different artists, names as follows:
For all I have jpg-files with an explanation of the opus with the name
Strauss-J2_op354.jpg (substring of filename) which should appear for each artist's version.
With 1by1 this one jpg-file is shown in all different mp3-files (file-name starting with identical Strauss-J2_op354).
I know how to integrate them into the mp3-files manually with mp3tag - but approx. 500 times ...
Who can help ? What is the more efficient, elegant and less boring way ?
Thanks and regards, Bernd.
