Play unplayed first & genre tags

[jdg072]

I am new to minimserver and have 2 questions to start.

1. I used to tag genre as "Jazz" and if it belongs to multiple genres "Jazz;Blues". That worked on my LMS squeezbox, but not as good as I wanted on minimserver. How can I get these songs displayed in both genres seperatly, instead of displaying a category as "Jazz;Blues"?

2. The main reason to come back to my owned music is that spotify "algorithms" me what to listen to. Everytime the same 100 songs out of a playlist om 1000"s of songs.
So has Minimserver a way to give preference to least played music first if shuffling all songs?

Many Thanks, Johan
