Animation Stop when Streaming Audio stops

Hello there !!

I have a problem, I have made a nice little animation with a start and a stop button. When I press play the animation starts and so does a streaming sound (1 minute & 30 sec) (and when I press stop it all stops aswell) but I would like to know if there is anyway to control the animation so it stops when the streaming sound has ended ? … I would like the sound to be streaming to reduce the file size.

Thankfull for answers !!!
