user1458: If been pondering about this one for a while and seen some of them pop up. How far are we allowed to go with questions that don't directly affect an anime but a more Regular like question about anime such as:
Will you ever "grow out" of anime? —
other example on site
I know questions like;
What is your favourite anime soundtrack? — other Example on site
are not appreciated

user27: Questions about anime in general are allowed, and encouraged. We don't need in-universe questions only.
Look at the FAQ for example:

Anime and Manga - Stack Exchange is a Q&A site for enthusiastic anime
  and manga fans. This includes questions about:

Plot, character, or setting explanations
Historical or societal context of an anime or manga
Anime and manga identification
Franchise/series reading or viewing order
Anime and manga production
Tropes, terminology and other general anime and manga related information.


Not all of these are directly on specific anime.
The second example you gave is a list question, we've had a chat discussion over it and defined rules about questions whose answer is a list. You can read it here: What is the status of list questions on this site?
