I used GetChildren() on a folder and it didn't get the children. Help?

I'm trying to make background music play, and it's not getting the children of the folder, "Music" which contains the songs. I used the function I made, nothing happened. I tried to print the songs. Nothing happened. Help please!

local Songs = script.Parent.Music:GetChildren()
print(Songs)
local function PlaySongs()
    for i, v in pairs(Songs) do
        v:Play()
        while v.Playing == true do
            wait()
        end
    end
end

PlaySongs()

script.Parent.Music.MiiMusic.Played:Connect(function()
    PlaySongs()
end)
