K-POP Tube – Popular & Recent is a free music app that allows you to watch and play the most popular K-pop music videos. It has a simple and intuitive interface that allows you to browse through your favorite K-pop songs by year, genre, or artist. Besides, you can also find the most popular videos from all time, and even sort them by most viewed or by most recent. You can also choose to watch any video using the built-in player or the official YouTube app (usually it should be already installed on your device). It contains a K-pop history of 13 years, so you can watch any video you want to see.
