"APT," the catchy collaboration between ROSE of BLACKPINK and Bruno Mars, has become a massive streaming hit worldwide since its release on Friday, Oct. 18.

In its first four days of release, “APT.” earned 13.32 million U.S. on-demand streams, according to Luminate, while also topping Spotify’s global and U.S. daily streaming chart, according to billboard.com.

The same report said the song's daily streaming numbers also represent a positive sign for its continued momentum, as “APT.” started with 3.57 million U.S. streams on Friday and cracked three million daily streams for each of the next three days while also selling 5,700 downloads over that opening four-day period.

It didn't take long for the "APT" to be mashed up with a local novelty song, "Saging Saging" (Banana Banana), resulting in a fun video featuring women doing exercises. It was uploaded by Ange Lucas on Facebook.

As of 5:15 p.m. on Oct. 26, the mashup video has been played 5.2 million times. Check it out:
