Together for more than six years years, 2PM is the first to admit that they "have been through some very hard times." But throughout it all, Wooyoung, Taecyeon, Chansung, Jun.K, Junho and Nichkhun have continued to create music that not only becomes more meaningful to them, but seemingly tells their story as a group.

In addition to asking the sextet about their world tour, in-group rivalries and how they unwind, Billboard also asked 2PM to pick the five songs that mean the most to them. Watch the latest episode of Billboard's Gimme Five series below:

While certain tracks get picked for different members' creative contributions or for the memories they evoke, Nichkhun says one non-single song, in particular, "speaks well" for 2PM and "always brings [them] up." Find out what song it is -- and their four other picks -- above.
