As we previously announced Wonder Girls have pre-released 3 new tracks for its American market.
The girls introduced the new songs during their iHeartRadio concert last week and now we can finally take a closer look at one of them.
On a recent interview, with Sunset from Clevver Music TV, the girls performed an a capella version of the new song "Wake Up", which is originally an upbeat track.
Check the video below and share your comments about this new song!
