Oricon has released the first sales data for Splatune 2, the official soundtrack for Splatoon 2 released in Japan.

On its first week, Splatune 2 sold 18,007 units in Japan. It debuted at number four on the bestsellers album charts, which is an incredible feat for a video game album. However, Splatune 2 fared worse than it’s predecessor, the original Splatune soundtrack for Splatoon. Splatune moved 43,000 units during its first week in Japan when it launched in 2015.
