I didn't know that Jieun had made a comeback until a few days ago. Surprisingly, this song wasn't composed by Duble Sidekic. Unsurprisingly, Jieun's title track is composed to Duble Sidekick.
I read that this song was supposed to feature Bang Yong Guk but thank God almighty that shit fell through. Bang Yong Guk single-handedly made "Going Crazy" go from a great track to one that I listen to once in a while. His severe lack of flow is so unappealing that I would rather rip out a goat's entrails and squeeze the shit out into my mouth than to listen to Bang Yong Guk's rapping.
I love how the song starts off with the piano, gradually adds the guitar, and then the song goes all out once the chorus comes around. The song builds up effectively to the chorus, which is strong without having to rely on vocal wanking. That is honestly the main reason why I love Jieun because she doesn't vocal wank in her/Secret's songs and stays within the framework of the song. Good vocals can add to a song and make them sound better if the vocalist isn't trying to outshine the song's instrumental.
The song is supposed to be about accepting unconventional love and all that hippy shit, but the real travesty is that the MV director didn't take advantage of the chains around Jieun to show her in bondage. Now that would have been an awesome MV, not because of the bondage scenes, but to see Korean keyboard warriors complain about the music video. The director missed out on a golden opportunity here, and that's really the only blemish with the song and music video.
