We absolutely love, love, love, Song Ji Eun's "Going Crazy (?? ??)," so for us to post a cover of this song, it has to be impressive. Well, Lillian Lee (an allkpop idol finalist and MBC Star Audition finalist), performed a cover of this song feat. Mark Agustin, and we adore it. �Lillian's vocals are as powerful and smooth as ever and Mark's English rendition of the rap is just fierce.
