Using MS Powerpoint 2007

Was wondering how to string 3 songs together in succession so that one plays after the other is finished. 
 
I have tried right clicking the animation and delaying the time, but that only works if you stay on the same slide, and if i try pressing "play across show" it auto resets the delay.

dude... awesome pic.

maybe if ur good enough u can edit the music so u can put three songs in a track and have the music long enough for the slide.
