trouble with Audirvana and multipl artist tag

[pask]

I'm lost...
Can someone help me to figure out how to tag correctly for Minimserver to get all infos about :

- multiples artistes (mostly for jazz) : Anouar Brahem is playing on his last album (Blue Maqams) with Dave Holland, Jack DeJonette, Django Bates. I'd like to see in artist list this album related to all artists. Going to Dave Holland artist will show me Blue Maqams on his album, like Anouar Brahem.

- Multiples styles : I'm big ECM lover, fantastic label. I'm since now using a 'ECM' label in the tag to browse my collection faster. BUT ECM is sometime editing musiciens from Jazz, classical, or contemporary music. How could I display some albums in different gender (ECM & Classical or ECM & Jazz)

- extra tag : Conductor & Orchestra are essential, like composer for classical/contemporary music.

What would be the best software to get/buy for tagging a list of FLAC/M4P/MP3 and 2500 albums to feet all this criteria and be 100% compatible with MinimServer on a Mac ?

I wish I can get someone to help me on that. I'm sure the question has been asked millions of time, but still can't figure it out, and if I have to retag my all library, I'd like to make it durable and effective (it took me a lot of time via Audirvana and was working fine, but since I want my music to be played without computer, only from the NAS to the DLNA Amp, I scared I must restart my tagging method from scratch

Thanks
