Find the most popular quizzes

The first step of this challenge is to get an output like this:

quiz_id: 1622, times_played: 24
quiz_id: 4964, times_played: 22
...

Now add the quiz title to this output

quiz_id: 1622, times_played: 24, quiz_title: Pokemon
quiz_id: 4964, times_played: 22, quiz_title: Cities!
...

A small tip

If you use the data files with the dates like 4_2015_01_2017_01.json you will find that the titles, answers and names look strange like: B56FT. This is only because we want to decrease the file size.
