How Do I Wait for Character to Load?

I have been trying to figure out how to create a script for a character to load first before the other scripts take place. I have been trying to figure this out because I need a sound to play in an area when the character has touched the brick that has the sound in it, however, it only plays for two seconds and then stops because the character is not fully loaded in. Anyone know how to make a script to wait for the character to load? Here are my music scripts.

script.Parent.Touched:connect(function(part)
    local plr = game.Players:GetPlayerFromCharacter(part.Parent)

    if plr then
        script.Parent.MufiaPlaza:Play()
    end
end)

Here is the second script for when the character leaves the "Part."

script.Parent.TouchEnded:connect(function(part)
    local plr = game.Players:GetPlayerFromCharacter(part.Parent)

    if plr then
        script.Parent.MufiaPlaza:Stop()
    end
end)
