text: how can i get a song to continuously play throughout a powerpoint presentation? i am making a presentation and i put the icon in the master slide for the song i want to play. it plays, but stops every time i click the mouse and restarts for each slide. help please! go to custom animations (slide show >> custom animation).  right click on the sound object in the custom animation list and select effect options ... then set the desired length of play under "stop playing."  you can also set the sound file to loop continuously through the slide show.  good luck!  *** edit *** don't put it in the slide master - put it on the first slide and follow the instructions i noted above.
