Is it possible to filter music by given fields within the current specification?

Hey everyone,

First of all, i tried to make my situation as clear as possible, please bear with me.

I have been using LMS (which supports open-subsonic) for a while now, but my use-case was always missing.
Therefore i had to patch the subsonic API for LMS.

Since LMs uses the open subsonic API I would like to discuss my use case, and whether we could think of a way to implement it within the open subsonic borders ( or maybe think of an API extension).

My use case is as follows.

I have a lot of music which is categorized in genre, subgenre, year and rating.
I categorize my music with mediamonkey.
I (mis)use the mood tag for subgenre.

This makes it possible for me to create a playlist on the fly with these fields.

I currently use /getMoods to return a list of moods
and i use /getSongsByMood to fetch me a list of songs.

/getMoods is a sort of copy of /getGenres
/getSongsByMood is a sort of copy of /getSongsByGenre

Currently /getSongsByMood has the following required parameters: mood
The following are optional: count, year, ratingMin, ratingMax

Currently /getSongsByGenre has the following required parameters: genre
The following are optional: count, year, ratingMin, ratingMax

What i try to achieve is that i can get a list of songs with several filters.
(and also fetch the filter values, like with getMoods etc.)

As far as i know, this is not currently possible in the current opensubsonic spec.
What are your views on this usecase?

Hello!
Thanks for your post. Needs are actually gathered here: #57
IMO, combining multiples filters (AND) is quite straightforward and should be easy to implement for all servers.
