Girls' Generation's 2014 EP, "Mr.Mr.", features "exciting" R&B sounds with "cool, simple" melodies. AllMusic's Heather Phares also noted inspirations of EDM, hip hop, traditional K-pop sound, and late-1980s europop on the EP, which she labelled "a set of songs that offers something for every kind of Girls' Generation and expands their musical reach." The group's 2015 album "Lion Heart" brings back their signature bubblegum pop sound; its third single "You Think", however, is a hip hop song that incorporates trap beats in its instrumentation.
