Only recommended if the genres are so different from each other, that you never, ever could stand to have them within the same play queue. (As some ppl feel with heavy metal vs classical music)
In general, if you really want this to work in Plex, you should bring your music library into order.

Always maintain a folder hierarchy of
Music > Artist > Album > Songs
