My music gui doesnt work?

So today i am working on a music starter gui that will play music and change the title when a different music is played. The gui says the music but the music doesnt play! It works in solo mode but in actual mode it doesnt. Please tell me what is wrong with my script. AIW is music so is TDFW.

music = game.Soundscape
while true do
    script.Parent.Text = "Now Playing: Turn Down For What"
    music.TDFW:Play()
    wait(5)
    music.TDFW:Stop()
    script.Parent.Text = "Now Playing: Am I Wrong"
    music.AIW:Play()
    wait(40)
    music.AIW:Stop()
    script.Parent.Text = "Now Playing: Its Raining Tacos!"
    music.IRT:Play()
    wait(10)
    music.IRT:Stop()
end
