DATE ogg tag doesn't work in iTunes

  • Why doesn't the DATE ogg tag show up in the 'Year' column of my iTunes playlist, while it does work in QuickTime player, and the other tags work fine?
    I have made some 'smart playlists' which group together 60's, 70's, 80's... music, but with no date information available to iTunes, this doesn't work very well of course...

    By the way, the ogg tag specification states that the tag identifiers are case insensitive. However, they only work in QT and iTunes when typed in uppercase...
