ok try this man, I know you have not looked at this in awhile but this should work.
for the first loop add a sound marker and have it point to the song file you want played. choose this as the main .fpi (
soundinzone.fpi) and then time out how far in the map you get before the loop ends and then place another sound marker with this for the main
repeatsound.fpi and have this file point to your second cut. or you could just get ahold of cool edit pro and splice the two together and create one .wav file for the game, I think Sony's Acid can splice as well.
