I'll start. The guy posted that message shortly after creating his account, So I'm guessing it's simply a test message? But judging from the fact that it's the only message he ever posted, And his somewhat weird profile pic, This raises more mystery than solved...
I could not resist this google and amazingly it is a song by Puerto Rican singer Luis Fonsi featuring Puerto Rican rapper Daddy Yankee from Fonsi's upcoming studio album. Fuck.
