After ending her "Black & White" promotions earlier this year, G.NA is back with another hot song called "Top Girl" on today's episode of MBC's�'Music Core'. As the title track of her second mini-album (also of the same name), "Top Girl" aims to energize the crowd with its infectious dance beat and fun chorus lines, which goes, "I'm a top girl / tok tok tok /glamorous like a hot girl".�The song was also produced by�Kim Do Hoon and had lyrics written by Wheesung. Check out her comeback stage below, which also includes "Without You"! It would have been "Banana" if not for the ban by MBC earlier.
