Trying to make a audio/Radio Script but it does not seem to work. why?

So im basically trying to make some radio thing but it doesnt let me stop the audio thing or put in a new one. If there is a better way to lay this out or if there is something else wrong with this please tell me :] Local Script For ID

local TextButton = script.Parent

TextButton.FocusLost:Connect(function()
	local replicated = game:GetService("ReplicatedStorage")
	replicated.MusicID:FireServer("MUSICIDENTERED", TextButton.Text)
end)

Local Script to Play Music

local TextButton = script.Parent

TextButton.MouseButton1Click:Connect(function()
	local replicated = game:GetService("ReplicatedStorage")
	replicated.MusicID:FireServer("PLAY", TextButton.Text)
end)

Local Script To Stop Music

local TextButton = script.Parent

TextButton.MouseButton1Click:Connect(function()
	local replicated = game:GetService("ReplicatedStorage")
	replicated.MusicID:FireServer("STOP", TextButton.Text)
end)

Server Script

local replicatedStorage = game.ReplicatedStorage
local DJModel = game.Workspace.DJ
local Music = DJModel.MusicID

replicatedStorage.MusicID.OnServerEvent:Connect(function(player, Check, musicID)
	if Check == "MUSICIDENTERED" then
	if game.Workspace:FindFirstChild("Music") == nil then
	local NewSound = Instance.new("Sound")
	NewSound.Parent = game.Workspace
	NewSound.SoundId = "rbxassetid://"..musicID
	NewSound.Name = "Music"
	NewSound:Play()
	elseif Check == "PLAY" then
		if game.Workspace:FindFirstChild("Music") then
			if game.Workspace.Music.IsPlaying == false then
				game.Workspace.Music:Play()
	elseif Check == "STOP" then
		if game.Workspace:FindFirstChild("Music") then
			if game.Workspace.Model.isPlaying == true then
				game.Workspace.Music:Pause()
			end
		end	
			end
		end
	end
	end
end)
