How do i use remote events smart so i don't need to create five instead of only one?

So i created a music gui, and when u click a play button its going to play, but on the server. so when u click on the play button, then its going to fire a event, and its going to play and everybody can hear it, but what if i then want so if the player click pause and it fires the same event. its just going to play the song again. if that makes sense.

Client script

local RE = game.ReplicatedStorage:WaitForChild("RemoteEvent")
script.Parent.Play.MouseButton1Click:Connect(function()
	if script.Parent.TextBox.TextBox.Text ~= "" then 
	local Plr = game.Players.LocalPlayer
	local Asset = game.MarketplaceService:GetProductInfo(script.Parent.TextBox.TextBox.Text)
	script.Parent.SongName.Text = Asset.Name
	script.Parent.UploadedBy.Text = "Uploaded by "..Asset.Creator.Name
	RE:FireServer("rbxassetid://"..script.Parent.TextBox.TextBox.Text,"Play")
	end
end)
script.Parent.Pause.MouseButton1Click:Connect(function()
RE:FireServer("rbxassetid://"..script.Parent.TextBox.TextBox.Text,"Pause")
end)
script.parent.Stop.MouseButton1Click:Connect(function()
	RE:FireServer("rbxassetid://"..script.Parent.TextBox.TextBox.Text,"Stop")
	script.Parent.SongName.Text = ""
	script.parent.UploadedBy.Text = "Uploaded by nobody"
	script.Parent.TextBox.TextBox.Text = ""
end)

Server script

local RE =game.ReplicatedStorage:WaitForChild("RemoteEvent")
RE.OnServerEvent:Connect(function(sender, ID,Gen)
	if Gen == "Play" then
	local Character = sender.Character
	if not Character:FindFirstChild("Sound") then
	local Sound = Instance.new("Sound",Character)
	Sound.SoundId = ID
	Sound.Looped = true
	Sound:Play()
	end
	if Gen == "Pause"then
	Character:FindFirstChild("Sound")
	end
	if Gen == "Stop" then
	Character:FindFirstChild("Sound"):Destroy()

	end
	end
end)

u can see i tried with the if gen == "Play" then but it dosn't work

Are you sure you have written out your full script? If yes, then...

    if Gen == "Pause"then
    Character:FindFirstChild("Sound")
    end

You'd add in :Pause() to pause the music:

    if Gen == "Pause"then
    Character:FindFirstChild("Sound"):Pause()
    end
