YouTube API V3: Where can i find a list of each 'videoCategoryId'?

Question

I'm using the Youtube API V3 but can't find documentation for how to filter by category:

Here's my code:

$results = $youtube->search->listSearch('id,snippet', array(
    'q' =>                  $_GET['q'],
    'maxResults' =>         20,
    'type' =>               'video'
    'videoCategoryId' =>    'what-do-i-put-here?',
));

I've been going through their documentation for an hour and can't seem to find any reference to how I find out what the various category's ids are. In my case I'm looking for the videoCategoryId for music....
