A simple question about the soundcloud API, but I can't find this info, and can't make the test by myself since I don't have a pro account: If a user update (replace) a file, how could I know it? Is the id replaced? Or the date changed? Thanks

No, there's no real indication for that in the API response, but I guess it could be the case that the original_content_size changed.
