Hey Seth,

The function is actually called in the video. If you look in the "printSongs" function, he calls the function "print(listHTML)" near the end. Basically all it does is print the list that he created to the website. Its use here is only for visual purposes. All he wants to do is print that list to the webpage so you have some visual feedback that the program you just created worked.

It's really just a simple print function for javascript, since javascript doesn't really have the visual feedback some other programming languages have in a console. Sure you can use chromes console, but its hard to write functions there and see their results.

Cheers!
