Looping externally loaded swf files

I’m trying to load external .swf files into a blank MC on the main timeline (using loadMovie). The external files contain music (1 track in each .swf). I want these .swf’s to load one after the other and then loop back to the first .swf again (like a CD player set to repeat all songs). What kind of script can I write to accomplish this?
Note: In the external swf files, the sound is in a MC called audio. No other frames exist in the .swf.
Also, what’s the best way to script button controls that can stop, play, fwd to next track or rev to next track??


This is a bit complex… I’m just bumping it to the top in case someone wants to take a crack at it.
