The noun after "more than any" can come in the singular or plural form.The statement that the structure should only take a singular noun is totally groundless.
She is younger than any other students in her class.(plural,perfect)
(Rg:She is younger than any other student.
If no context is given for this sentence,I can be absolutely sure this example was coined by a Chinese author of English grammar.It is a perfect example of Chinglish.)
He liked Zurich more than any other city/cities.(singular or plural,perfect)
At that time I liked coke more than any other drinks.(plural; nothing wrong)
Tom's a big fan of Lady Gaga; he loves her songs more than anybody else's.(singular,perfect) (You use "anybody else" (singular!) because you don't want to say "any other person".)
GOOD LUCK!
Dya wanna more examples?I reckon it wouldn't be necessary to have any more other than those provided.
