Howdy @support and everyone.
For lack of a better place to discuss this (since it relates to metadata, however does not entail a problem) I’ll post here.
DDEX has released a new metadata format Media Enrichment and Description (MEAD).
MEAD has some pretty wild and exciting types of information that it can contain, such as Dance and Rhythm Style, Instrumentation, and Historic charting information.
Is it cool or what? Is it coming to Roon? Lets discuss!
Seeing as the existing fields aren’t exactly universally filled in now do you really see this being used?
Well, it certainly sounds very interesting. But when I read:
Implementers of the ERN standard will therefore find it very easy to implement the new standard.
I cannot but think that it is the cue for hollow laughter…
Edit: yes, I am old and cynical, but I’ve served my time on Standards committees… 
I think… that… the issue with metadata isn’t that we can’t fill in enough information, it’s that the information itself is not standardized enough to make sure that there is exactly one value for what should be unique data, for example exactly one way to write Johann Sebastian Bach.
The recent Forbes article misses that one important point, but does point out the exciting potential for all the new information:
The standard defines a syntax for messages that labels can pass to digital music services (and others) when they release new records. Many labels already use a DDEX message standard called ERN (Electronic Release Notification) to send digital music services basic information about new releases. MEAD messages augment ERN messages with detailed information about the music. MEAD also defines a rich model of metadata fields, which is embodied in 50,000 lines of XML code and a 4500-row spreadsheet. The fields include types of artists, artistic influences, similar artists, related artists, artist biographical details, name pronunciations, genres, subgenres, vocal registers, instrumentation, time signatures, rhythms, tempos, moods, lyrics, studio locations, historic chart data, awards (e.g., Grammys), etc., as well as a few fields specific to classical music such as periods, opus numbers, and composer catalog numbers (e.g., Köchel numbers for Mozart works). It also contains fields related to “focus tracks” that labels want to promote for periods of time. The metadata can include photos and writeups of concerts or tours.
Yes, that is cool new information, very rich data. But it doesn’t help at all if you want to find music by Bach, and there are three ways to write his name.
The classical guys on the forum would take exception to the thought that the current fields are filled in 
More is always better, I appreciate that!
