About Track Properties

Shown below is a table of all properties stored in the Library vs. which properties are stored in Tags. 'Yes' indicates that the information is included in the tag, 'No' indicates that it isn't, and 'Non-Standard' indicates that it is included, but that no clear stardard exists for how this field should be tagged, and consequently it may not be readable by other media players.
