I am in the process of developing a music quiz application that integrates the Spotify API to play songs in the background, allowing players to guess the song's name and artist. Upon investigating the requirements for extended quota mode, I discovered that creating a game, including trivia quizzes, is prohibited under the Spotify guidelines:

III. Some Prohibited Applications

   2. Do not create a game, including trivia quizzes.

(https://developer.spotify.com/policy#iii-some-prohibited-applications)

What is the reason behind this restriction? Would it not benefit Spotify to allow developers to create engaging games using their API that require its users to obtain Spotify Premium?

Additionally, are there any exceptions to this rule, such as obtaining a written approval, or would you recommend alternative services that permit such integrations?
