Need some XML / Flash help...

I've got an MP3 player using XML. The AS in controlled in the Flash buttons.

As of now, when you click the previous or forward buttons, it correctly goes to the requested song, but it takes a foolish amount of time to load. (There is dynamic text to show the progress)

I've seen and used other players with longer songs that load instantly (or the songs were preloaded)

I'm looking to insert a command into the XML that preloads all of the songs, leaving zero amount of load time. If I need to do this in the actual Flash document, that's cool too.

Can anyone lend their talents and assist me? Thanks!
