Note that InitialKey and BPM are not currently indexed fields. We can certainly index them, but each field index brings some DB writing performance (and DB size) penalty, so I would rather avoid indexing all fields.
Alternatively we could avoid indexing them completely (like in case of 0018760) -- with just small node expanding time penalty.
Are you suggesting it adding as additional subnode under collections like:
Music --> Initial key
?
Maybe it would make more sense to be under Classification subnode?
i.e.
Music --> Classification --> Initial key
?
Assigned to Rusty to review for which fields it makes sense to add them to the tree (as available node) and where + default states?
e.g. 'Intial Key' might be visible by default for Classical Music collection?

Re: Re BPM I agree regarding not full re-index as it can impose penalty. As for INITIAL KEY it is very very specific TAG which as shown at attached picture is fixed value and Unknown Value. It is very important for Mixing similar tracks and needs to be available as quickly as possible, also very useful for Auto-DJ where with some good Scripting MM can be programmed to be a DJ by itself if you provide it big enough library.
Re NODE: INITIAL KEY have more in common to fingerprinting than classification as it represents music key of a track, so its place is in root not in classifications, but not available by default as normal users mainly do not have use for it.

Of the recently added metadata attributes, the following might be useful in the tree, though I'm really not sure about how many users would use this. e.g. for a DJ's purpose, the Column Filter might be a better means of filtering based on Initial key.
Language
Initial Key
Energy
I don't think that any of these should be enabled by default.

Language, Initial Key, Energy are already part of 'Column filter'
Collection > Classification > Initial Key is already part of Media Tree
Added 'Language' and 'Energy' in build 3527 |
