My tracks are simply called, because, well why not, it's not like I'm ever going to look at them, or search for them, and it takes memory to store those names e.g.I've only tested 3 systems with MP3, OGG and FLAC, but found that Sonos doesn't like embedded art in MP3's with ID3v2.4 tags (and I refuse to use ID3v2.3) and MinimServer doesn't display embedded artwork for Ogg Vorbis files, so having CD folders with folder.jpg means I can easily convert from one format to another. I have CD folders under album as I've found that having folder.jpg instead of embedded album art is more compatible with other devices/software.

I don't have any singles and only a handful of EP's, so if you wanted to add that layer into the folder structure to ensure it's unique that would make sense (but again, make sure it's also available in the tags, I often use this to subset my music when browsing). I use %releasedate% in the folder name (although I do browse by %originaldate%) simply because it makes it more unique, as like you I have many remasters of the same album and in all but a handful of situations this resolves to a unique folder name (in those other situations I fill another tag with supplementary information to make it unique - which is used by foobar2000 to create the folder structure).To that end I have a similar structure to your first one with a couple of tweaks: The folder structure should support carrying out other functions e.g.To achieve this my folder structure is created based on tags available in the music files themselves. Make it easy to QA your music collection including folder structure.I have albumartist artwork as well as other albumartist metadata so I want a single place to store it and all their albums. Have a single place to store all related information e.g.Make it as simple as it can be whilst being unique, because that's all it needs to be, you shouldn't be browsing by folders (or navigating the file system) in 2022!.I have a couple of underlying principles:
