How do you make a song play when the player steps on the brick that the song is in?

i am making a war for cybertron game and when the player steps on the brick it plays the trailer song kinda like a cutscene. i tried to do:

game.Players.PlayerAdded:connect( function(plr) newsound = game.Workspace.Part.Trailer:clone() newsound.Parent = plr.PlayerGui

newsound:play() end) but it did not work. Any other suggestions? if you want to fix it then send it to me heres the model: http://www.roblox.com/War-for-cybertron-trailer-song-item?id=153472370
