For anyone interested in running Walkout Song DJ on a Windows laptop... there is an excellent free Android emulator called Bluestacks that runs very well on recent laptops. I have been able to install Bluestacks, Walkout Song DJ, and the Simple Song Collector. Full screen, it makes a pretty sweet combo if you are tired of trying to use a tiny phone screen.
Bluestacks will also run on an intel based mac laptop if you have one of those around.
