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)
