Does that music video you’re watching have a suspiciously high rate of visible brand names? Are your headphones reminding you that you haven’t yet bought that new thing that everyone’s talking about? If so, there’s a good chance that the song is a CM single, an advertisement song for a product or service. Companies in South Korea put idols’ popularity to good use and hire them to promote products for them. We’ve collected 10 of our favorites for a little product placement parade! Fair warning:  try not to spend all your money on your favorite idol’s product — save some for whatever they’ll be promoting next year, too. Using well-known faces and voices to promote a product is a genius move in itself and adding idols into the equation creates the perfect storm of chart-topping music that everyone will hear, idols that hoards of fans look to for fashion and lifestyle inspiration, and a product that has now entered the minds of an entire target audience.
