Using music as a mantra

Ok, im going to try another WILD attempt tonight and I got to thinking about a Mantra to use while im attempting the WILD. I struggle to think of a phrase that means something personal to me that would help as a mantra.

Then I got to thinking, does it have to be something as simple as a spoken phrase, why not something more transient, like a song or music.

So my question is, does anyone else imagine music or a song as a mantra? or do you think thats too distracting?

Thanks!

Have you ever heard of binaural beats?

I have heard of that, but its surrounded by mixed review, and I would have to wear headphones.

I mean, inventing your own tune in your head, and using that.
