de/activate audio listener via collision? (or click?)

Hi there, I’ve been playing with unity for awhile, but am only now starting to program. I’m not asking for a script, but recommendations as to what functions I should be using to make happen what I want to.

The current project (not really a project, more just space for me to F with) is this

I’d like to make it so that you could either hit the box (some sort of collision) or click with with the mouse to make the music pause, then hit/click it to make it play.
I’d prefer if the music started out not playing.

So I guess what I want to know is, do I just put a script in the gameobject with the audioplayer? And what functions would control the play/pause part?

Let me know what you think, thank you.

Pretty much this: Unity - Scripting API: Collider.OnCollisionEnter(Collision)
and this

Unity - Scripting API: AudioSource.Stop or just audio.enabled = false;
