There are always new unexplored corners of Windows Media Player ready for experimentation. Usually when I'm in the Library pane, I live in one of the Artist or Composer views. This evening, I expanded the
Year Released tree to see what was listed.
First up, you see that the
Year Released tree is based on the
Date Released field, another of those "let's give every field multiple names" cases in WMP. (See the article on Artist fields on this site, for more examples.)
The expanded nodes start with "Unknown" (ie no data in the field) and then range sparsely from 1899 to 2019. As noted in the WMP Library bug-list, WMP likes to add or subtract 1 from some year ranges, so "1899" in the
Year Releasednode corresponds to "1900" in the
Date Released tree. This bug has been around since before v9 was released. It's also noticeable in the way that Windowsmedia/AMG album descriptions are usually one year different to the year that is downloaded as track metadata.
[2006 update]
Apparently this bug affects all users whose systems operate forward of GMT timezone i.e. GMT+X. Will there be a fix, or will that wait until the US somehow moves into these timezones...?
The few nodes with years > 2005 just have a random selection of tracks that have been mis-labelled. I discover to my surprise that I cannot erase the field (and thereby shuffle these tracks into the Unknown node) or drop the tracks directly onto the Unknown node. All I'm left with is changing the field to another number, so I bulk edit the tracks to be "1900" which um...naturally drops them into the 1899 node. The Advanced Tag Editor does not give you access to this field, so that route is also closed off. I'll probably have to edit the tracks in another program to clear this field.
So, while the layout of trees is visually similar for
Album Artist, Contributing Artist, through to
Purchased Music there is a fair amount of variation in the way they actually behave. Some are single-valued fields (e.g. Album Artist, Album) where a semi-colon delimiter
cannot be used to group a track under multiple headings. Others like
Composer, Contributing Artist and
Genre are multi-valued: the semi-colon delimiter can be used in this fashion. Within the latter group, there is the further difference that drag-and-drop works differently for
Genre. If you drag a track to a
Genre node, you are given the option to Change or Add Genres. I find it peculiar that this option does not exist for the other multi-valued fields. And then of course we have the single-valued
Year Released which does not allow you to drag tracks onto the Unknown node. This restriction does not exist for the other fields discussed. I *really* hope that none of the folks who designed this have anything to do with WinFS or other metadata-handling elsewhere in Windows UI.
I'll mention in passing that there is also a "Period" field that accepts text, so you could write something like "Baroque" or "1940s". This is somewhat redundant given the multi-valued Genre field already allows me to create such labels. If the "Period" field were coupled with a left-hand pane tree view it might be more useful, so that chronological categories weren't lost amongst the thematic Genre items.
