Think of it this way: other applicants will follow the directions, and you'll be one who didn't. If there are, say, 100 applicants, the best way to narrow focus is by eliminating applicants that didn't follow the directions. They may want to have all the recordings in one place for convenience and consistency, so make it as easy for them as possible and use the platform they request. If you go against the grain, you might be elimiating yourself before they even listen to your recordings.
