I use winamp with ASIO. Windows can not shutdown if winamp is playing music. It seems that ASIO driver block the shutdown process. I tried pause the music first, then windows can shutdown smoothly. So I am looking forward someting like ONSHUTDOWN event. The PAUSE cmd code can be added on that event.
read my other post... nix asio (if wdm drivers avail)

Sun, Come shine my way
May healing waters bury all my pain
Wind, Carry me home
The fabric of reality is tearing apart
The piece of me that died
Will return To live again
