This guide is for those who want to fix their music.

Step 1: Download Notepad++

Step 2: Open the file TCGLoadingTCBoombox.lua in notepad++ and vinylplayer if you use vinyls.
This Can be found in User/Documents/Zomboid/Workshop/(ModName)/Contents/mods/(Modname)/42/lua/server/Items.

Step 3: Using the find feature make sure to mark match case. And use the replace feature.
The Devs renamed some spawn containers.

First being WardrobeMan and WardrobeWoman
using the find feature replace all instances with WardrobeGeneric.

Next the above may have renamed WardrobeManClassy and WardrobeWomanClassy to
WardrobeGenericClassy for me it happened sometimes but either way all instances change to WardrobeClassy.

The Final Container is BedroomSideTable for whatever reason the devs renamed it to BedroomSidetable. So just replace all instances of BedroomSideTable with BedroomSidetable.
This should fix every error and keep cassettes spawning properly in those locations.

Step 4: This is optional but to increase the spawn rates replace every 0.01 with 2.5 and every instance of 0.05 with 3.0 using the replace tool mentioned above. I found this optimal you can tweak this however you want.

An Added note you will need to redo these every time you add or remove music.
