Running LMS 7.9.1 - 1522157629 on Debian 8 X86_64, and I have recently discovered SQL Playlist. I see some references in the forum saying that it does not work well with recent versions of LMS. So far it is working well for me, but I am struggling to get it to do some things.
I do not know SQL, nor am I familiar with the structure of the LMS database. I have general experience with relational databases and Boolean expressions. Following some basic online guides to SQL, I have tried to apply those concepts. So far, nothing has worked.
Specifically, I want to make use of multiple genre tags. For instance, I have many files with the genre tag, 'Jazz'. Some of those files also have a genre tag that says 'Xmas'. (There are many more files that have the 'Xmas' genre tag, along with some other genre, and a few that only have the 'Xmas' tag.)
My goal is to set up a playlist that only plays files that have both 'Jazz' and 'Xmas' tags. All attempts so far have failed miserably.
Here's the code generated by SQL Playlist for a playlist that plays only 'Jazz':
So far, I have attempted to another line to the 'where' section, like so:
I have tried different groupings of parentheses, without success.
I also tried doubling the 'where' section:
Again, no luck with several variations on that format.
Is what I'm trying to do possible? If anyone is willing to share some hints about the right way to do it, I will be very grateful!

where
audio=1
and dynamicplaylist_history.id is null
and genres.name in ('Jazz')
group by tracks.id
order by random()
limit 10;
Code:
and (genres.name in ('Jazz')
and genres.name in ('Xmas'))
