How to organize and tag classical music

[Suth]

Hi,
I am happy to share my experience with tagging classical music and you'll understand why i ended up using minimserver and nothing else.
I tagged my music with Foobar that is highly flexible. For Classical musical i created additional fields like area (Baroque, Classical, middle-age, etc...), performer (I use the composer as artist), instruments, tone, country. And for title, i reference the catalog number when it exists rather than a name (BWV for Bach, RV for Vivaldi, etc...) and i created a movement field. It is created with a number to indicate which movement it is and additional info like adagio, andante, etc...
I have done that to be able to find quickly in Foobar a given composition. Other name commonly used is refered as a comment.
Then i had to find a server able to display this information in a readable manner. In Minimserver, i have merged title and movement to see what i was playing. Anyway, the track number puts everything in the right order, but it is useful to see what you listen.
The only thing i am missing in minimserver is conditional choice. For exemple, i would like to do actions only if the track belongs to classical music. It would enable me to have the right view for each type of music.
If any of you have an idea, he is welcome !
