Where to insert code for Soundy plugin track title?

I want to add the track title to my Soundy plugin on/off button. Soundy says to add code <?php soundy_title(); ?> or

“To display the audio track title in the content of posts and pages, use the short code: [soundy title].”

I can’t find the right page and/or line to put this.

This is the site. Any help is greatly appreciated.
