That's just one of the song titles. When you attach a numeric value in brackets to an array name, you are indexing or sub-scripting the array to reference just one of the values. In this case, since the array is a playlist, this will be one of the song titles.

The code in the video is combing it with HTML tags to display it on the page. This is done in a loop so each title is displayed by number order. The result of doing this is demonstrated in the video.
