SQUARE UP is the third EP of BLACKPINK’s SQUARE music series following single albums SQUARE ONE and SQUARE TWO in August 2016 and November 2016, respectively. This is the first album that was released with a physical album by the YG Entertainment quartet and features title track “뚜두뚜두 (DDU-DU DDU-DU)”, and B-track “Forever Young”.
The mini-album includes 4 hip-hop, electropop songs that match contemporary hit radio.
The physical version of the album also included an hidden track, which later was revealed to be “
마지막처럼 (AS IF IT"S YOUR LAST)”.
In an interview, Rose of Blackpink said:
The title of our first mini album is Square Up, which means to get ready for a fight. The tracks are songs we’ve been working on since our debut. The lead track is very nice, but check out our other tracks as well!
