This mod fixes a base game bug where the Boombox plays different songs between the client(s) and host.
This is technically a client-side mod, since it just synchronizes the clients randomizer to the seed of the host. But I would recommend for everyone to install it anyway. This mod should be compatible with other Boombox mods like Custom Boombox Music.
Thank you to Steven (the creator of Custom Boombox Music) for helping me figure out what exactly caused this bug <3
