Super Junior will be greeting fans through an 'SM Station 2' song before their comeback.

Super Junior will have their repackage comeback on April 12th with 'REPLAY'. But before that, they'll be releasing "Super Duper" through 'SM Station 2'. Fans have actually heard the song already through their 'Super Show 7' back in December last year.

Leader Leeteuk participated in composing and writing the lyrics for the song, and it's a fun, addicting song.

Check out the covers below.
