Button doing function reverse?

I'm making a mute button to mute elevator music for my elevator game, I'm making a mute elevator button so players can mute the music in the elevator, But I wrote a code and it doesn't work, I've been trying to fix it for 2 hours now, May anyone help please?

The problem is that it doesn't play at first, When it's supposed to be off it is and the button is on, When it's off it says off and plays music, I press it again, Still plays music and says on.

My codes

DisableMusic Local Script

local on = true
local player = game:GetService("Players").LocalPlayer

local musicParent = workspace:FindFirstChild("Elevator"):FindFirstChild("TimerPreview"):FindFirstChild("MusicPlayer")

script.Parent.MouseButton1Click:Connect(function()
    if on == true then
        on = false
        game:GetService("ReplicatedStorage"):FindFirstChild("Mute"):FireServer()
        script.Parent.BackgroundColor3 = Color3.fromRGB(85, 255, 0)
        script.Parent.Text = "On"
    else
        on = true
        game:GetService("ReplicatedStorage"):FindFirstChild("Unmute"):FireServer()
        script.Parent.BackgroundColor3 = Color3.fromRGB(170, 0, 0)
        script.Parent.Text = "Off"
    end
end)

Section of MainHandler aka the Elevator script. Note: I am running the function

function chooseRandomSong()

    if chosenSong == false then

        local allMusic = musicFolder:GetChildren()

        local randomMusic = allMusic[math.random(1,#allMusic)]
        local cloneMusic = randomMusic:Clone()

        for i, player in pairs(game:GetService("Players"):GetPlayers()) do
            if player then
                if player:WaitForChild("MutedMusic").Value == false then
                    game:GetService("ReplicatedStorage"):FindFirstChild("UnmuteClient"):FireClient(player)
                else
                    game:GetService("ReplicatedStorage"):FindFirstChild("MuteClient"):FireClient(player)
                end
            end
        end

        cloneMusic.Parent = musicPlayer

        game:GetService("ReplicatedStorage"):FindFirstChild("Mute").OnServerEvent:Connect(function(player)

            if player:WaitForChild("MutedMusic").Value == true then

                game:GetService("ReplicatedStorage"):FindFirstChild("MuteClient"):FireClient(player)

            end

        end)

        game:GetService("ReplicatedStorage"):FindFirstChild("Unmute").OnServerEvent:Connect(function(player)

            if player:WaitForChild("MutedMusic").Value == false then

                game:GetService("ReplicatedStorage"):FindFirstChild("UnmuteClient"):FireClient(player)

            end

        end)

        local songNameDefault = cloneMusic.SoundId:match("%d+")

        local songId = cloneMusic.SoundId
        local newStr, replaced = string.gsub(songId, "rbxassetid://", "")

        local songName = MarketPlaceService:GetProductInfo(songNameDefault,Enum.InfoType.Asset).Name

        print(songName.." has been selected as song")

        game:GetService("ReplicatedStorage"):FindFirstChild("UpdateNameGui"):FireAllClients(songName, newStr)

        chosenSong = true

    end

MusicMain Local Script

game:GetService("ReplicatedStorage"):FindFirstChild("MuteClient").OnClientEvent:Connect(function()

    for i, v in pairs(workspace:FindFirstChild("Elevator"):FindFirstChild("TimerPreview"):FindFirstChild("MusicPlayer"):GetChildren()) do
        if v:IsA("Sound") then
            v:Stop()
        end
    end

end)
