These stupid Category numbers are everywhere but it is hard to find the official classification so you don't know what the hell they are talking about.

Category 1 Spoken Word (2 subclasses)
Category 2 Popular Music (4 subclasses)
Category 3 Special Interest Music (5 subclasses)
Category 4 Musical Production (5 subclasses)
Category 5 Advertising (3 subclasses)

Check out the site for all the details. The titles make sense when you read about them.
