Just minutes ago, I posted a note that I was taking suggestions for the music to accompany a particular chapter. Then, I saw this thread.
I have used mood music in most of the chapters of my novella. I particularly appreciate the option of going back later in editing and adding music after I've found an appropriate track.
In my first chapter, I used a track from Midnight Syndicate. MS is a fun duo of music composers who create soundtracks for roleplaying games and for movies which never existed. I strongly suggest that other Tapas creators browse this group's Soundcloud collection. https://tapas.io/episode/746935
In my second chapter, I used a track which I found by chance on Soundcloud. It's called Alchemy by Mabowsky.
In my third chapter, I went to my favorite band, Random Encounter. RE was known primarily for its amazing covers of video game music. The small Orlando rock band also released a good amount of original work, including this track. It's Galaxy of Friendship, a track from an actual video game soundtrack that RE created shortly before the band broke up.
I have another track picked out for later, but it doesn't quite match my Chapter 4. MAFX also provided the theme for my netcast (podcast) show. https://soundcloud.com/mafx/fried-chicken-grease-96bpm
