I found myself having to migrate a MP3 collection off a Brennan JB7. This was good new as the JB7 wasn't fit for purpose in this case. I exported the MP3s, and the catalogue to a text file. I was surprised to discover the JB7 does not apparently use MP3 ID3 tags.
The script below corrects this by applying the catalogue data from the text file to the MP3 metadata.
Use at your own risk!

title = big_list[lineno - 2]

title = big_list[lineno - 3]
artist = title

artist = title.split(' / ')[0]
title = title.split(' / ')[1]
if artist not in cd_dict:
cd_dict[artist] = {}

lineno += 1

print("processing {} of {}: {} .".format(processed, len(cd_dict.keys()), artist))
