Music files that will play over multiple slides

Hello,

I was able to add an MP3 music file and have it start playing with the click of the mouse, but when I go to the next slide the music stops. I'd like it to keep playing but I haven't stumbled accross the instructions of how to do it.If it's in one of the online documents, please include the page number.

Please help.

I didn't find the right solution from the Internet.
