Q: Question: Did Hamasaki's pop ballad or more rocking song have a better chart position? Passage:It opens with two club-driven tracks: an interlude titled "Bridge to the Sky", and the promotional titular song. "Disco-munication" is the second interlude on the album, blending "sophisticated" electric guitars with electronic music. "Energize" is another electronic track, and is one of the only numbers on the album that include English phases ("Put your hands up together, keep your heads up forever, let me sing forever,"). The fifth track "Sparkle" was noted as a club song with an electronic arrangement, similar to the follow-up song "Rollin'". Both tracks feature autotune and vocoder pro-tools, a first for Hamasaki. The album's sixth track, "Green", shows a departure from the album's earlier electronic style; it focuses more on older traditional Japanese sound, alongside instrumentation of electric guitars and drums. The album's third interlude, "Load of the Shugyo", was described as an "atmospheric" number with heavy rock instruments in its composition. Rock music is then influenced on the following tracks "Identity"—a song that discusses about self-confidence—the single "Rule", and the tune "Love 'n' Hate", which talks about the effects of lust. The album's fourth and final interlude "Pieces of Seven" was noted for its "atmospheric" sounds of an ocean, until the second half of the track diverges into a harder rock style. "Days" is the album's first pop ballad, and is described as a love song. It closes with the ballad "Curtain Call", which features a choir and piano riffs throughout its composition.
