How do a make a background music that doesn’t start over at the end of frames, but does loop once it’s finished playing?=)
mySound = new Sound();
mySound.attachSound(“myMP3”)
mySound.start(1000);
This should help, don’t forget to name your sound in the linkage menu.
Hope this helps

I still need more help 
Can you give me step by step instructions?
<B>mySound = new Sound();</B> - Create a new sound
<B>mySound.attachSound(“myMP3”)</B> - pull the mp3 song out of the library (myMP3 = the filename)
<B>mySound.start(1000);</B> - Start your sound loop and loop it 1000 times.
Attach these actions to a frame, not a movie clip.
