Using a mobile wireless technology networking seems to be the next logical step in flexibility and usability to combine these technologies of digital music and wireless connectivity.

All you need to do is tell your music/video player to use the "bluetooth" output device. Some players, like Audacious and Amarok, let you specify this in their preferences.
