Would someone care to explain why Gangnam Style has become such a meme that tech startups are tempted to reuse it for marketing purposes? I mean I listened to the original song on Youtube and it didn't strike me as particularly worthy of listening to again and again, let alone bringing it up in conversations with other people.
Because it's popular, so it gets clicks. It's popular because it's the fad of the moment. It's a fad because it snowballed. It snowballed because something has to be snowballing, as people want to pay attention to something, and they want to do that as part of a group. This is that something because it's cute, nicely produced, vaguely edgy but not threatening to anyone, and it got lucky.
