The first version in the very early days of 128kbps mp3 seemed to be more popular before people were ripping and encoding music with proper id3 tags. Once it became a defacto standard for proper artist, albumname, tracknumber id3 trags to be embedded as metadata in the mp3, using some sort of automated tool very quickly took over.
I do recall using several different tools about 20 years ago that took a bunch of horribly mangled filename .mp3 files (but which did have proper id3 tags in them, or where the user had manually corrected the id3 tags for the bare minimum of albumname, artistname and track numbers) and then rewrote their filenames on disk to something logically consistent to make them easier to find and move, store, copy manually if needed.
I remember going through and manually keying in the id3 tags on my mp3s using WinAmp, because without them the dash between the artist and song look slightly different. That was a lot of work over a dash.
The more I think about it the more there needs to be an ID3 equivalent to video media so the meta data is stored with-in the movie container versus a central database.
Kodi and their meta helpers can create a local meta file. Next step is to push it into the media container.
CppCon and other video recorded events would benefit from this. The shared video file would contain the details and remove the energy to search for the source and other meaningful information.
