Best of 2015: 2015’s must-hear albums include Janet Jackson’s ‘Unbreakable,’ Ty Dolla Sign’s ‘Free TC’

Kendrick Lamar, “To Pimp a Butterfly� (TDE): Pulling from free jazz, Parliament-Funkadelic era funk, slam poetry and live instrumentation helped Lamar craft the year’s toughest listen. “To Pimp a Butterfly� spoke directly to black America and provided the necessary soundtrack in the age of #BlackLivesMatter.

Kehlani, “You Should Be Here� (self release): The year’s finest R&B album came from a largely unknown 20-year-old. Self-assured tales of romantic yearning and heartbreak are woven over refreshingly bright productions reminiscent of early 2000s neo-soul. Kehlani’s versatility is astounding as she flips among being earnest, hopelessly optimistic, lustful and inspirational.

Janet Jackson, “Unbreakable� (Rhythm Nation): With her comeback album, Jackson focused on connecting her groundbreaking past to a present that’s still deeply affected by her influence. “Unbreakable,� her first album in seven years, took the fusion of R&B, funk, disco and rock that drove her early discography and added a more mature spin — without chasing the trends of current pop.

Dawn Richard, “Blackheart� (Our Dawn): “Blackheart� saw Richard set fire to genre boundaries. Freewheeling narratives of loss, redemption and triumph are funneled through Greek mythology, sci-fi and trippy experimental polyrhythms. “Blackheart� is the year’s strangest listen — singular, exhausting and addicting.

Jazmine Sullivan, “Reality Show� (RCA): Using the drink-throwing, backstabbing betrayal of trashy reality shows as inspiration, Sullivan crafted a witty character study with her third album. The beats are heavier, but her sumptuous vocals about vanity, pain and self-love never sounded so sweet.

The Weeknd, “Beauty Behind the Madness� (Republic): His “Beauty Behind the Madness� straddled the hazy, drug-and-sex-fueled alternative R&B that made him an Internet sensation with expertly crafted pop tunes. It’s dark, sexy hedonism without regret or consequences.

Fifth Harmony, “Reflection� (Epic): Not since Destiny’s Child retired its stilettos has a girl group come close to mattering in pop music. Despite its manufactured start, Fifth Harmony beat the odds and released a smartly produced album. Loaded with dance anthems and R&B grooves, the album delivered sass and carefree effervescence in equal parts.

Shamir, “Ratchet� (XL): The 20-year-old Las Vegas singer with a countertenor that could pierce a cloud put out one of the year’s most vibrant debuts. Between his soulful approach to sweaty disco-house sonics and the youthful vigor of his lyrics, “Ratchet� is a pure delight.

Ty Dolla Sign, “Free TC� (Atlantic): Hip-hop’s favorite hooksmith took the blend of R&B and “ratchet� rap that made him a mixtape sensation and expanded it with stripped-down acoustics and sticky pop beats. The lyrics are brazen (raunchy, even), but his sandpaper rasp is intoxicating.

Drake, “If You’re Reading This It’s Too Late� (Young Money): Drake’s surprise mixtape isn’t about big ideas and concepts. Instead, he opted for mood. The beats are murky and hypnotic. There are plenty of seductive hooks, but his usual vulnerability took a back seat to assured raps showing he’s well aware that he’s at the top of his game.
