Why does this simple code not play the song?

Hey guys! I have this code for a radio. I checked all sound ID's, and tested each separately. They're correct. But with this code, the songs don't play. Why?

while wait() do
    songs = script.Parent:GetChildren()
    rando = math.random(1,#songs)
    if songs[rando].Name ~= "Script" then
        workspace["Now Playing"].Value = songs[rando].Name
        songs[rando]:Play()
    end
end
