Can you name every one of the 39 licensed themes LEGO has ever produced sets for?

Excluding the four LEGO movies, which were licensed back to LEGO by Warner Bros.
Although the Back to the Future sets are licensed ones, they don't fall under a licensed theme. Instead they are part of the Ideas, Dimensions, Brickheadz or Icons (not wholly-licensed) themes. It would be fun to do a quiz with every licence LEGO has ever had, but that would be a very large number of answers!
Interesting - Brickset categorise Ben 10 as "Constraction" and do not put it in the "Licensed" category. However, it is both licensed and a full theme of its own (rather than a subtheme like the cases of the other comments). On this basis I would say it does qualify, and I will add it to the quiz in due course.
like ferrari, bugatti, lamborghini etc
