After releasing her comeback mini-album, "Heartmade," singer JOO has finally made her comeback on today's episode of Inkigayo with her title track, "Bad Guy"! "Bad Guy" is a pop ballad produced by E-TRIBE and features an impressive string arrangement that aims to differentiate JOO from the other ballad singers in the market.� The song has been doing exceptionally well on the charts so far, and although she suffered a bit of criticism from her shaky Music Bank comeback, music fans have been applauding her vocal talent nonetheless. JOO commented, "I'm excited about my first comeback in two years.� I'll make sure to do my best to show how hard I've worked for the past two years, so please look forward to my comeback."
