Background audio file type and location

[Mitd9922]

In windows media player, what do i specify for a location that I can use for the show? I created a song list to use for background audio, but when I try use it it only lets me pick one artist and not the whole list. i know I'm a bit new to the BA player but I need a little more detail on how to get the whole playlist into the BA. Thanks for any help!

And if this is the wrong thread, please send it to the correct location.
