When would you use sound channels?

Hello gang

Working my way through: https://docs.google.com/document/pub?id=149g_P1YlE4_6v_hHbFx3YAaYpdU0HoM70XJSLTE38ww#h.p8jj7h7pend7

And I'm wondering what would be a case to use sound channels at all?

Why not just use:

music:play() ?

Thanks

But basically you just use music:play()
Only play works as a constructors and create an instance of what you are playing. Thus you can create one Sound, and play it multiple times (creating new channel every time) and manipulate them (pause, volume, etc) separately.
