As I stated here
Those categories [i.e. "genres"] like "working out", "reading", "falling asleep", " are coded with two digits numbers. It is not that hard to remember them, especially when you skip some and group them thus use something like 61, 63, 65 and 72, 74, 75 with 88, 88, 89 [but not 62, not 71, not 81 and 82 etc.]
And those RPG-genres [RPG music categories] also have numbers but I display them with names [e.g. "dungeon", "cosmos" etc.]. But the numbers on them are also important because they are used by my cleaning action for putting them, with all of the others categories, in a predefined order [Moving part of TITLE to GENRE - #6 by Zerow]. And "RPG" does not mean "just when playing role-playing games" but also when "reading a certain book" or "trying to illustrate a certain video"
I personally really find it quite pointless and way too much time wasting to wonder about "is this song hard rock and progressive rock or only progressive" [or whatever "legit" combinations you can think of / stumble upon]. But maybe that is more obvious to me as songs in my collection and tracks done by bands are less than 50%, with majority of the music being instrumental, mostly from various scores
And even my RPG-system seems to me sometimes as being time wasting. Because in the end all you need to know is:
- mood
- tempo [and if they are changes in it]
- "modernity" [are the sound more electronic / futuristic or traditional / made with old instruments]
- vocals [are the any words, vocalizations - or nothing i.e. just music]
