Harry Styles’ long-awaited fourth studio album, “Kiss All the Time. Disco, Occasionally,” was finally released on Friday. The highly anticipated album was preceded by the single “Aperture,” which topped the UK Official Singles Chart, the Billboard Hot 100 and the Billboard Global 200.

As we’ve come to expect from Styles, “Kiss All The Time. Disco, Occasionally,” combines the essence of pop music with alt-rock and classic pop elements. One could say that the vocal range and emotion are missing in Style’s voice, or you could argue that it just enhances the meaning of the album. The humility of the album comes through in its honest lyrics and less extravagant singing compared to Styles’ previous releases.

During an appearance on Britney Broski’s “Royal Court” YouTube series Styles said that he hates when artists don’t make something for themselves. “Kiss All The Time. Disco, Occasionally,” makes perfect sense in the context of that remark. It’s a personal diary entry and an exploration into issues like anxiety, therapy and blissful ignorance in relationships. The alternative classic rock inspirations help create an individual, mature tone with often overwhelming moments.

There has always been a sense of melancholy and deep emotional confessions in Styles’ albums, which has helped create a sense of congruency between his pop genre explorations, despite their sonic variety.

“Coming Up Roses,” the eighth song on the album, is an example of this variety. It diverges from the synths and guitars that appear on the rest of the album by introducing an orchestra, foregrounding Styles’ exceptional singing abilities. While Styles, Tyler Johnson and Kid Harpoon composed most of the other songs on the album, “Coming Up Roses” demonstrates the fruits of Styles’ solo writing efforts.

The album is split between a depressed pop and an excited disco, which makes it feel like a background album compared to his more energetic past releases, but the vulnerable lyrics and synthesis of contemporary and retro musical elements reflect Styles’ growing maturity. “Kiss All the Time. Disco, Occasionally,” is different from what many may have expected from Styles, but not unwelcome, and it’s bound to grow on audiences.
