One button for two events?

Hi guys

here is my question

i know that if i want to do off on sound button in flash i can make 2 buttons then use a behaviour for each of them

ok , what if i want only one button that when clicked will stop sound playing , and when clicked again plays the sound , that is one button for the two events

another thing is what about if i want to make three buttons , and each when clicked plays a music
