Sound and the timeline

i have a game i am working on. its liner based( all sections of the game are on the time line) each section is in a mc on a different frame in the time line.

how would i go about adding sounds to each section?
i tried playsound/stop sound but it seems to stop all sounds after i execute it once. then i was thinking of having the names of all my mp3 in an array and playing them from there.

i haven’t used sounds much in flash yet and was wondering the best way to go about it. I’m open to any suggestions

thanks
