On Friday, March 18, 2016, JY dropped her first solo EP, titled Radio, consisting of three tracks. Out of the three, two music videos were produced and released on her official Vevo and YouTube channels. Radio was composed by London-based songwriter and producer MNEK, while Darren Craig directed the music video for Radio.
