The reason is simple.
You know that in mania, a keysounded (Customized hitsound) map doesn't have anything that we called "BGM"... They have "virtual" as their BGM, hence are not possible to use the "drag-in" common way when you create standard maps.
Just have a button that can let us create a map from nothing is OK.
