Here is a Mediainfo dump. File type is mp3.

Interesting.
I wouldn't be surprised if MPD uses different libraries to deal with the different media file-types, with lots of room for inconsistent behavior. I still need to look at mp3 tagging in general. My only mp3 files are transcriptions of radio dramas, podcasts, and the like and neither consistently nor comprehensively tagged.
For completeness, here's what mediainfo reports on a file tagged just slightly differently to the file whose metaflac output I reported a few posts ago:

Writing library : libFLAC 1.2.1 (UTC 2007-09-17)Note that 1) it automagically converted all-caps tag names to "proper" names except my new "NAME" tag?!?, and 2) it reported out the four separate genra lines in the file as one combo line.
Added in edit: There's no requirement in the Vorbis comment spec for the tags to follow any special capitalization rules. I just entered "NAME" to be consistent with the rest of the tags in the file I had downloaded. Apparently some (many?) of the tag editors can be configured to enforce uniformity rules.
