3,442 PointsI did not add a comma after the first array, which gave me an error on line 14. Don't you love debugging as a beginner?
const playlist = [
['So What', 'Miles Davis', '9:04'], <---
['Respect', 'Aretha Franklin', '2:45'],
['What a Wonderful World', 'Louis Armstrong', '2:21'],
['At Last', 'Ella Fitzgerald', '4:18'],
['Three Little Birds', 'Bob Marley and the Wailers', '3:01'],
['The Way You Look Tonight', 'Frank Sinatra', '3:21']

Quick tip, use the "markdown cheatsheet" linked under the comment box to format your code next time for easier reading. Like this:
```javascript
code goes here
