To stream music on Myspace, you need to find it somewhere online in asx format (i.e. you need an address like "http://www.tuxjunction.net/media/mp_ladance_1.asx").  Once you have that, copy and paste that address into param name=Filename and Src fields (the highlighted fields) in the code below.  Once you've done that, simply copy this entire code into any of the profile areas where it says HTML code is allowed and your profile will contain music!
