Girl group f(x) is making an explosive comeback, and fans all around the world have been following the success of it all.

The idol group's new album, titled "Red Light," which was released on July 7, has managed to top various music charts both in Korea and internationally.

f(x) ranked No. 1 on the iTunes charts in Hong Kong and Singapore on July 9. They were also seen ranking in the "Top 100" on iTunes charts in 23 countries, including Malaysia, Indonesia, Taiwan, Poland, Japan, Peru and more.

The title song, "Red Light," dominated music charts in Korea, ranking No. 1 on a total of eight sites, including Melon, Mnet, Olleh Music, Bugs, Genie, Naver Music, Daum Music and Soribada, according to Yahoo Celebrity Philippines.

For those who have yet to listen to the album, "Red Light," consists of tracks that classify in the electronic house genre, mixed with bits of urban and house beats as well.

f(x)'s latest album consists of 11 tracks, with collaborations from major composers, including Teddy Riley, Thoma Troelsen, Kenzie and Hitchhiker.

Billboard published an article on July 8, detailing the transformation of f(x) with their new single and album.

"A zippy, phat bass line, ticking clock, snare drums and stadium-sized clapping open 'Red Light' featuring members Krystal and Sulli's confident coos. By the 22-second mark a hip-hop brass drop is added, at 0:37 the track is growing into an epic EDM buildup until the chorus hits at 0:52, turning the song into a hyperactive, synth-pop banger," writes Billboard's Jeff Benjamin about the group's title track.

He adds, "The track continues in a similar, jerky fashion, adding vocal layers, hair-raising harmonies and ad-libs to the addictive melodies at will. While it'd be tough to not label the bubbly-gummy hooks as pop, the aural twists and turns give the track an exciting, exploratory element, forcing the listener to listen again to catch the different parts."
