I think that something is also correct in this sentence. Is it so? Is there a difference of meaning between something and anything in this sentence?

[Vinnfred]

You usually use something in affirmative and anything in negative or interrogative sentences

something should also be correct as well. Without more context it can be understood as anything or something
