Ring Tone I Don’t Understand [OT]

Maybe somebody here can figure this out…

My wife phoned me yesterday; and instead of a default ring, I heard… well, the wrong kind of Ring. I heard “Ride of the Valkyries.”

Which would be fine, except I never set that as the ring tone for calls from my wife’s phone. And I don’t have that music in my phone. Anywhere.

Nonetheless… Ride of the Valkyries

The next time she called me, I heard the usual default ring tone — so I  have no idea what happened earlier. The most logical hypothesis at this moment is that this wasn’t a ring tone at all: at the very moment she called me, an army of Valkyries just happened to be flying past.

(She later decided, by the way, that she wants that music to be her ring tone on my phone — specifically, the Elmer Fudd cover version)
