More longer friend see that sky?

The aliens could not have picked a worse week to invade. Ironically, everything went wrong because everything went exactly as planned. The giant warships appeared unannounced in the sky one day, doing nothing but gathering data for the upcoming assault. Humanity, being in shock, did not attack these warships, on the off-chance these utterly armed machines of war came in peace. Then, after enough information had been gathered, the invasion began. Humanity was defenseless against the psionic assaults, and most surrendered without firing a single shot. In the annals of planetary conquests, this was one of the neater ones.

Until the aliens stopped to think about it, and about what they had conquered. And, being psionic, about what those they had conquered had thought about.

The weeks prior to the attack, a new genre of music had swept the world off its feet, gathering massive amounts of people dancing in the streets. It was not known then, but this genre was the closest humanity could come to a psionic virus at its current technological level. As the aliens surveyed what they had conquered, so too did they listen to these beats. To say that it made their heads explode would be an overstatement, but they did suffer greatly before dying.

Needless to say, global art spending and investments increased manifold over the coming decades.
