You're just missing a comma.

On line 4 of two-dimensional.js, you need a comma at the end of the line.

Great. How did you find it? I eventually also saw it. The console doesn't specify line 4. Is there a JS lint program somewhere?

When the console complained about trying to read a property of undefined in printSongs, I listed playList out and found that item 3 was indeed undefined.
