Simple one button html5 audio player

Would really appreciate som help with this. Is not all that great with code.

I need to create a one button audio player.

The button can be an image or a button with text toggle Play/Pause.

Also if someone knows, it would also be great if it could use different playlists. So you have one pause play button, and then three different buttons for different playlists. This isn't a priority, but would be great.

Ps. I am going to use this on a wordpress site, if that matters.
