how do you tag your MP3s?

Mar 21, 2010 14:33

MP3s ripped from CDs or bought digitally (usually) come pre-tagged, including "genre". "Genre" has an eclectic set of options including folk, rock, soundtrack, children's, Christmas, gospel, international, electronic, and electronica/dance, to name just a few. Some CDs of Jewish music came tagged as Christian (!) or gospel, and I changed those to Jewish (a new category) at the time. An MP3 can have at most one genre (hence options like folk-rock, I guess).
Some of these genres are orthogonal to each other. Jeff Wayne's "War of the Worlds", "Pirates of Penzance", and "West Side Story" are all soundtracks, but they are not similar musically. Children's isn't a genre; it's an audience or application. "Nowell Sing We" and "Rudolf the Red-Nosed Reindeer" are both Christmas songs, but they're not the same at all (I would sort the former with "early", another category I had to invent because "classical" just doesn't fit the middle ages and renaissance). (Ok, I wouldn't have the latter in my collection, but work with me here...) I have no idea what the difference between "electronic" and "electronica/dance" might be, and how the latter differs from "dance".
I think the makers of the tagging system conflated style and purpose. We're running into this a lot with international dance music (often dances are set to folk songs), or with everything from folk to blues to rock ending up together because they're "Jewish", or SCA dance music being scattered across "SCA" (this must have been a custom category for someone), "dance", "classical", "folk" (?), and probably others. And I'd like to be able to tag the subset of folk music that is children's music (for selective exclusion), without losing its folk-ness.
I'm coming to the conclusion that the correct way to do this is to use "genre" for what it is musically and some other tag for usage (if it has a primary usage). Looking at the tags available to me in iTunes, it looks like I should use "grouping" for this. (I've never seen this field filled in, so I don't know what conventions surround it.) So early music is early music and some of it might be grouped as "dance", folk is folk and rock is rock and some of each might be grouped as "Jewish" (or perhaps "Jewish liturgical", since that's what I'm really after), and the Hebrew folk songs that are used for Israeli dances would "folk" (genre) and grouped as "dance", and so on. (Maybe we want to distinguish SCA dance and international folk dance; that's an implementation detail.) But before I try to do anything along these lines I'd like input: how do you capture multiple dimensions of your music? (Another option, just to throw it out there, is to use playlists as buckets. We're doing some of that but it doesn't feel sustainable to me.) I want to be able to find music by genre or by purpose, which says to me I want two searchable fields.
We are currently using the comments field to support tags iTunes doesn't give us. For example, there's no off-the-shelf way to tag the language of a song! So for the languages we care about we have entries in the comments field like LANG_HEBREW. We're also doing something similar to tag the Child ballads (TAG_CHILD_#_) so we can easily find the dozen variations on "Maddy Groves" scattered through the library. (Child ballads are a special interest of Dani's.) We're also using this field for meta-data about our own recordings (e.g. TAG_WEAK); "comments" probably isn't a good place for that but those were the first tags we added so we grabbed the obvious field and now we're kind of stuck unless we want to do a lot of work.
A problem with using "comments" is that you can't systematically add to a comment field, only replace it. So if we wanted to use it for other tags (like usage) and wanted to apply those in bulk, we couldn't without stomping some of our existing tags. Well, we could write a perl script, I guess, but I looking for something a little closer to the GUI.
So how do the rest of you track extra information? Or are we the most finicky among our circle of friends? :-)
