Yes, but it would've been much more interesting to read about title drops where this is not the case. The top titledrops listed that are not names of a character are all names of something else, like locations or objects.
The problem is that there aren't any lists for title drops excluding boring cases like that. So all the lists get dominated by those cases.
That said, Barbie is a funny case indeed, as it's named after about half of its characters :P
