hello ^^

ok, i read the FAQ, took a look at the movie section, but didn't find what i'm looking for...
i'm currently doing a small game, and i have a backgroud music that loops; it's an attached sound in fact.

what i want to do with it:
the original sound file is composed with the intro music, and the part that is supposed to loop. i don't want the loop to repeat the entire music, just to play it from the begining (so with the intro) the first time it's played, then loop let's say at the middle of the track... is it possible to do it? or is it better to cut the original sound file and work that way?

thanks for your help ^^
