Reception
"High High" received acclaim from music critics. Spin named the single the seventh greatest K-pop song of all time, commenting that the track "grows gruffer and faster as it buttaflies [sic] higher and higher" and concluding "this is how LMFAO and Far East Movement want to sound." Billboard chose "High High" as one of T.O.P's most memorable songs, with Tamar Herman writing that the "G-H-E-T-T-O E-L-E-C-T-R-O" chant on the track's bridge "remains one of the most catchy and baffling moments of Bigbang's career." Additionally, the single's music video was named by Stereogum the fourth best K-pop music video of all time, with Tom Breihan writing that the track "does poppy American club-rap better than any American has done it in many years" and that GD & TOP "appear to be having more fun than anyone else on the global pop-music landscape" in the music video. Korean magazine Ize complimented that the song's uses the "club culture" boldly, and the result is "refined and digested".
