Songs that are in the same musical key as SW music
How many songs (that you have heard) are in the same key as a given SW track? For example: The Imperial March is in the same key as Selena Gomez - "Come and Get It" (g minor), while Yoda's Theme is in C Major (a lot of songs are in key with that one, such as Billy Joel's "Piano Man").
I wonder which galaxy (in the observable universe) looks the most like the SW Galaxy. I bet they can see ours.
