The material, particularly the "faster tracks" and cover songs: "Rydeen (Dance All Night)" by Yellow Magic Orchestra, "Koi no Boogie Woogie Train" by Ann Lewis, and "I Heard a Rumour" by Bananarama, were widely praised for the producers abilities to "reconfigure J-pop's past into the buzzing present." But once again, the ballad entries were slated for their "mood killing" appeal. For their third studio album, E.G. Time (2014), it saw a change in musical style, particularly with the uptempo numbers. Additionally, the band's management, LDH, hired a variety of new producers and composers to work on the album, namely Yasutaka Nakata, Lauren Kaori, Fast Lane, and husband-wife duo T.Kura and Michico. This was their first record to remove a large portion of ballad songs, having been replaced with "aggressive" EDM numbers and "twinkly" electropop anthems. According to Patrick St. Michel, writing for The Japan Times, majority of the recordings have the vocalists singing in unison, which has been a notable factor in various Japanese acts such as AKB48 and their sister groups; the writer identified "Music Flyer" as the most prominent example from E.G. Time. Subsequently, he felt the track re-introduced them back into the K-pop genre.
