Sound not replicating on the server?

I'm using FilteringEnabled, and the sounds .Ended event isn't registering, the song's properties aren't being updated on the server, only on the client. How can the server be notified that the song has ended?

local MusicLibrary = {"298810953", "378902218", "360676009", "256519229", "257739740", "446057463"}
local AmbienceLibrary = {}
-- War 256131892, 446883821

local Sounds = game.Workspace.Mechanics.Sounds
local Music = Sounds.Music
local Ambience = Sounds.Ambience

Ambience:Play()

ChangeSong=function()
    if (not Music.IsPlaying) then
        local Choice = MusicLibrary[math.random(1, #MusicLibrary)]
        Music.SoundId = "http://www.roblox.com/asset/?id="..Choice
        Music:Play()
        Music.Ended:connect(function()
        print(".")
        end)
    end
end

ChangeSong()
