Hi cagricelebi,
Thank you for the report. I have fixed it, however, I made it planets = {"nauvis"}
I like having distinct music per planet and I feel like this music fits Nauvis best. This is just my preference/opinion, feel free to modify/fork however you please :)
Here is some more nauvis music I recommend: https://mods.factorio.com/mod/original-music-hd-reloaded
Also, check out my other mods, there are music packs for Nauvis (this mod),
Space: https://mods.factorio.com/mod/ftl-music-space
Fulgora: https://mods.factorio.com/mod/into-the-breach-ost
All of them are music that I believe "fits" the planet.
I will do music packs for other planets in future if/when I can think of music that fits those planets.
