This chart is based 100% on the official ranking on South Korea's Gaon Digital Singles chart. Here you can find what some of the most popular K-Pop and Korean songs are this week [July 19th to 25th, 2015]. Obviously I don't agree with the position of some of these songs, but none of this chart is my opinion. It's based 100% on fact. These are the 20 most popular songs on the Gaon Digital Chart. :)
