'Jekyll' includes 9 tracks in all with 3 new tracks being "Jekyll", "You're Impressive" ('G.R.8.U'), and "What Do I Do".

"You're Impressive" is the title track and rather than utilizing the formal spelling of the phrase in Korean, the boys have opted for a more casual slang spelling seen used online to relate to their internet savvy fans. So for the English version, it seems they have decided to adopt that same theme by calling it G.R.8.U or 'Great You'.

The video teaser previously left us all puzzled as it gave us a sample of the song played backwards, but now you can finally hear the full song through the official release today. Check it out through the MV above and the other new songs through the playlist below!
