Very handy module.
I used it to write myself a neat little custom alarm clock, which plays nice relaxing wake up music gradually increasing in volume over half an hour.
And if that doesn't work, ramp the volume to maximum and crank out random techno or death metal.
More useful for sound, video appears in an uncontrollable window wherever the hell it wants to. And unfortunately, you can't load playlists.
But still a great module.
