Non-uniform tagging of music in iTunes Store

There isn't one team responsible for setting up the metadata, or any agreed standard on the best way to do things. There are many different companies that submit content to the iTunes Store, and when it comes to ripping your own CDs iTunes picks up track information from the Gracenodes CDDB database, much of which has been entered by different individuals with no attempt at a uniform style. The best you can do is develop your own scheme and tweak everything that you add to your library as you import it. Like you I put anything descriptive in square brackets. Because I still have older iPods which don't support album artist I put guest/featured artist information into the track title, again in square brackets, so artist can remain consistent across the whole album. And I Put Everything In Title Case.

See Grouping Tracks Into Albums for some background on iTunes tagging quirks.

As given, there is no one central team responsible for metadata. See this list of aggregators for example. This is a user to user support forum. Your suggestions for improvements should go to iTunes Feedback.
