Sting - "Out From the Shadows" by Jim Johnson

Kinda sucks as an song to play, but it's his WWE entrance song, as you usually play those. If you're not married to playing that, but still wanna hit him with a (WWE owned) entrance song.... hit em with "Man Called Sting" (https://youtu.be/O9hw-NDnft8), which actually has lyrics.

Some other old Sting entrance options.
