Play, pause, stop

Hi, this is probably a dumb question as always, and I did search for it this time, but couldn’t find what i was looking for

I took the tutorial on playing a sound file, but I want to know how to pause it, and stop it, eventually i want to do next and previous song buttons, but im not worried about those 2 for now.

This is the code I have
[AS]on (release) {
Finchsound = new Sound(this);
Finchsound.attachSound(“Finch3”);
Finchsound.start(0, 99);
}[/AS]

Finchsound.pause doesnt exist, so what would i use as an alternative, and also finchsound.stop didnt work

finally, if you click play multiple times it just plays the song again, so you have a ton of overlapping songs.

any help would be great

thanks a lot
