Adding Background Audio to my Program File

I am a virtual tour provider. My virtual tours, once posted online can be downloaded. When the tour is downloaded it downloads as an .exe file. However, if the virtual tour has audio playing in the background when it's online, the music does not download with the virtual tour. I need to be able to somehow embed music into the tour once it is downloaded or be able to put it onto a CD and have the audio play in the background once the tour autoplays (without launching another program like windows media player). I was unsure what "job type" this should be, but if anyone can help that would be greatly appreciated. I have attached one of my stand-alone virtual tours to this project so you can take a look at it. Also, if it's possible to create an app for me to do it myself or show me how to do it myself that would be greatly appreciated as well.
