2PM is a South Korean boy band established by JYP Entertainment in 2008. Consisting of Jun. K, Nichkhun, Taecyeon, Wooyoung, Junho, and Chansung, the group was formed after the members participated in an audition, with the exception of Nichkhun, who was scouted. 2PM made their debut in 2008 with the mini-album Hottest Time of the Day, featuring the lead single "10 Out of 10." Throughout 2009, the group enjoyed success with their second mini-album 2:00PM Time For Change. This was followed by their first full-length album titled 01:59PM, which soared to the top of the South Korean charts thanks to the hit single "Heartbeat." In 2010, 2PM expanded their performances across Japan and the US, participating in various music festivals. Over the years, 2PM has generated a series of albums for both Korean and Japanese markets. Their Japanese studio albums include All About 2PM (2011), Republic of 2PM (2011), Legend of 2PM (2013), 2PM of 2PM (2015), and Galaxy of 2PM (2016). Their Korean discography, on the other hand, includes albums such as Hands Up (2011), Grown (2013), No.5 (2015), and Gentleman's Game (2016), all of which have reached the top spot of the Circle Chart in their native country. After a hiatus due to members serving their military service, 2PM marked their much-anticipated return to the music scene in June 2021 with their seventh studio album, Must. This release marked their first in four years.
