That window shown in the second screenshot is just giving you the option to do a file swap instead of creating a new song. If you select "Create New Song", then a file conflict will most likely be detected and you will be given the same basic options as the first screenshot I believe. This was done because users were importing files to update existing songs instead of using the swap file feature, so I wanted to make it easier to do a swap by just dragging & dropping.
