3xxxv5 is the introduction track of ONE OK ROCK’s seventh studio album, 35xxxv.

With apocalyptic synths that foreshadow the tone of the next tracks, Taka speaks in barely understandable English and Japanese, both at the same time in the left and right channel respectively. The track slowly builds with all of the instruments blending together until the climax.

The introduction ends with a snippet of some rehearsals for “Take Me To the Top,” the album’s fast-paced and aggressive second track. This is immediately followed with John Feldmann, the bands' primary producer shouting “That’s exactly what I’m talking about!” in excitement, as the track ends.
