Im making a music changing script using a ModuleScript with MusicID’s

What is the issue?
Workspace.Others.BackroundMusic.MusicChanger:7: attempt to get length of a nil value

Music Changing Script:

local RepStor = game.ReplicatedStorage
local MusicModule = require(RepStor:WaitForChild("MusicModule"))
local MusicList = MusicModule.Music
local MusicInstance = script.Parent or workspace:WaitForChild("Others").BackroundMusic

while wait(1) do
	local count = Random.new():NextInteger(1, #MusicList)
	
	MusicInstance.SoundId = "rbxassetid://"..MusicList[count]
	
	if not MusicInstance.IsLoaded then
		MusicInstance.Loaded:Wait()
	end
	
	MusicInstance.Sound = 0.5
	MusicInstance.TimePosition = 0
	wait(.5)
	MusicInstance:Play()
	MusicInstance.Ended:Wait()
end

ModuleScript:

local Music = {
 1845554017,
 1836842889,
 1847853099,
 1843463175,
 1837861894,
 1843324336,
 1840005864,
 1842967125,
 4908301571
}

return Music

Your module script returns your table, Music. When you try to define MusicList, you are trying to get Music.Music, Which doesn’t exist (hence why it says get length of NIL value.)

You should replace MusicList with music module.

local RepStor = game.ReplicatedStorage
local MusicList = require(RepStor:WaitForChild("MusicModule"))
local MusicInstance = script.Parent or workspace:WaitForChild("Others").BackroundMusic

while wait(1) do
	local count = Random.new():NextInteger(1, #MusicList)
	
	MusicInstance.SoundId = "rbxassetid://"..MusicList[count]
	
	if not MusicInstance.IsLoaded then
		MusicInstance.Loaded:Wait()
	end
	
	MusicInstance.Sound = 0.5
	MusicInstance.TimePosition = 0
	wait(.5)
	MusicInstance:Play()
	MusicInstance.Ended:Wait()
end
