By Apr 14, 2021 Stray Kids has proven their immense popularity in Japan after their Japanese single "TOP" earned them their very first gold certification from the Recording Industry Association of Japan (RIAJ). "TOP" is the first Japanese track Stray Kids released in June last year. It served as the theme song for the anime "Kami no To- Tower of God-." The Korean and English versions of the single was also launched last year. The "TOP" single album also includes the B-side track "Slump," which was used as the ending theme song for the same anime. The boy group's 3RACHA, consisting of Bang Chan, Han, and Changbin, took part in composing, arranging, and writing the lyrics for these two tracks.
