Which namespace does this work belong in?

I busy myself with moving works off of Main/ and I've encountered a number of cases where I can't decide to which namespace something should go. Some of these questions may have been asked before, but there seems to be no general reference point for namespace issues. Maybe this could become a sticky thread for all media-namespace related questions?

For easier reference, I've numbered my questions:

• #1: Where do animated films go? They seem to be distributed rather inconsistenly over Film/ (Puss In Boots, Whats Opera Doc), WesternAnimation/ (Disneys Anne Frank, Snow White), Anime/ (Princess Mononoke) and Disney/ (Snow White And The Seven Dwarfs, Der Fuehrers Face).
• #2: There are a few songs which have their own pages ("Pirate Jenny"). Where do they go – to Music/ or to Literature/ ?
• #3: Where do composers go – to Music/ , or are they to be treated like other creators, which hitherto stay on Main/ ?
• #4: Where do Talk Shows, Game Shows and News Broadcasts go? I guess you could call these formats Live-Action TV but they're not really "TV series", as in Series/.
• #5: Am I right in assuming that Puppet Shows go to Series/ ?
• #6: What about “hybrid shows”, i.e. segment shows that incorporate both live action and animation? (e.g. Die Sendung Mit Der Maus)
• #7: Where to put picture books? I am thinking of books like Der Struwwelpeter and Max and Moritz — books that are really not complete without their illustrations. They are not (yet) ComicBook/s, but to sort them under Literature/ feels a little unsatisfactory too.
• #8: The rule is to put works into the namespace of their original medium. However, once in a while there is a work which is little known in its original medium, and almost exclusively known by its adaptation. I’m thinking of Das Boot, for example: there's a novel, but it is almost exclusively known by the Petersen movie.
• #9: Should One Book Authors who are invariably tied to a single work be treated as a creator or a work page rather?— Currently, we have Samuel Pepys and Herodotus, but shouldn't these pages be at Literature/The Diary of Samuel Pepys and Literature/The Histories rather?
• #10: There are cases where I’m unsure whether to use the English or the original title. Is there are hard rule that determines whether Der Ring Des Nibelungen goes to Theatre/Der Ring des Nibelungen or Theatre/The Ring of the Nibelung? Even Wikipedia uses the original title.

I'd be grateful for input.
