A one minute teaser has been released and this song is right up HyunA's ally. From the teaser, we get to hear more repetitive phrases, rapping and a little vocal from HyunA.
For a solo album, I was expecting to see a "change" from HyunA, but so far from the teaser, the song is too close for comfort and too similar to what 4Minute would sing.
