On March 14th, TVXQ officially released their title track, "Before U Go", from their repackaged album for "Keep Your Head Down." Moments after its release, "Before U Go" rapidly climbed music charts on MelOn, dosirak, and Bugs. Representatives of SM Entertainment introduced the song by stating, "'Before U Go' is a traditional R&B track with heavy emotions. Yunho and Changmin's vocals were put at center focus. The song is unique in that it moves not only according to melody, but rhythm is well. The song switches back and forth between an 8-beat and 32-beat vocal rhythm." Check it out below! Their full MV will be released on the 15th, followed by the offline release of the full repackaged album on the 16th.
