[SOLVED] Different versions of the same album

[nosferatu_cat]

This is  the primary weaknesses of tagging.  There is no universal standardization and there are always exceptions to existing tag databases.  It would be wonderful to have something like the Library of Congress system for recordings rather than having to rely on the less than comprehensive tag databases available.

It is also the very strength of tagging (or metadata in general).  Record the information you find useful in the way that works for you.  When you combine it with a tool that can read and present that information you are in a much more flexible and adaptable world than you would be if there was only one way to describe music.

Taking this case as  an example, the OP can do one of several things:

1. Change the Album Name tag to include the extra information.
   
2. Ensure that the tags include the MusicBrainz album ID and ask moOde to include that in it's key.
   
3. Ask moOde to include the folder path in it's key.
   
4. Use the Folder view in moOde (remember that the path to a file is also part of the metadata for which there is no universal standard).
   
5. Probably some other stuff too.
   

Thankfully, we have in moOde that tool that allows us to play with our data in this way

It's an in the eye of the beholder thing.  If you have music from different sources tagging can be a nightmare.  The same album or whatever you want to call it can have tags that differ.  E. g. composer:  J. S. Bach, Bach, Johann Sebastian Bach, 'Bach, J. S.'  Genre:  Blues, country blues, delta blues,...  I know, it's not so bad if you have software that can do "like" searches.  At my job we added attributes to a retail item database.  Users could enter text like music tags that pertained to items we sold.  We scrapped it after a year.  It was anarchy in the chaotic sense.
