Why pop stars want Starrah

Here's a quick piece of pop trivia: what do Drake, Katy Perry, the Weeknd, Rihanna, Calvin Harris, Nicki Minaj, Big Sean, Halsey, Maroon 5, Travis Scott and Camila Cabello have in common?

The answer, in addition to big market share: melodies written by Starrah, perhaps the most ubiquitous force in music who also happens to be completely obscure. An A-list studio presence for just two years, Starrah, 27, has tallied more than 6 billion streams on Spotify and YouTube alone - to say nothing of her innumerable radio plays - bridging genres and genders as a songwriter on 'Fake Love' by Drake, 'Needed Me' by Rihanna and 'Havana', Cabello's breakout single, which peaked at No 2 on the Billboard chart. Yet anyone would be forgiven for not recognising her name, let alone her face, which in images and videos is frequently animated and always obfuscated by a carefully placed hand, a K-pop-inspired panda mask or, if she happens to slip up and let a photographer capture her whole visage, an oversize emoji added after the fact.

The meeting

"I like my privacy," Starrah said with a believably shy grin at a recording studio in the San Fernando Valley earlier this month, at her first extensive interview. "The people I know who have fame would rather just take the money and leave the fame," she said. "I still live my regular life." Even in an industry known for its shadowy influences, the vocalist, born Brittany Hazzard, stands out for her anonymity and the improbability of her rise.

Raised in a tiny Delaware beach town, the youngest of nine siblings, Starrah cut her path through urban radio, crafting indelible, rap-sung hooks for strivers like Kid Ink and Dej Loaf ('Be Real'), Kevin Gates ('2 Phones') and Travis Scott and Young Thug ('Pick Up the Phone') before making the all-but-unheard-of crossover to the overwhelmingly white echelons of Top 40.

For Starrah, who is gay and can sing as well as she can rap, code-switching while remaining authentic to herself has always come easily. "I grew up in the ghetto," she said. "But around me, it was like a gilded curtain - everyone else was hella wealthy."

She attended Delaware State University, and became the first in her family to graduate. But on one early track, she sings of "PTSD from my childhood," a SWAT team kicking down the door. "I've seen both sides of the coin," she said.

Initially inspired by street literature like Sister Souljah's 'The Coldest Winter Ever' and female rappers like Eve and Nicki Minaj, Starrah also developed the omnivorous taste of the playlist generation. For some of her earliest compositions, she found acoustic covers of songs like 'Yellow' by Coldplay and improvised on top of them.

It was one such track titled 'Drank Up',which sampled the electronic song 'About You' by XXYYXX, that first caught the ear of Jarjour online. "I didn't know if she was a girl or a boy, 11 years old or 27 years old," he said, recalling the distinctiveness of her cadences. "She was the most ambiguous person I'd ever heard."

Starrah had moved to Los Angeles after college and was working at Urban Outfitters and Public Storage while pursuing music, posting now-deleted songs to SoundCloud and selling hook demos for $150 on Instagram. Jarjour was impressed by her work ethic, both out of the studio and in it: "From the beginning, Starrah sent more music than anyone else," he said, and she was very organised, a rarity for prolific songwriters. Gregarious, wide-eyed and relentlessly positive, Jarjour, 31, was also a complement for Starrah's sheepish humility, and he quickly became her protector and champion. Though her reticence toward fame has lent her career a marketable mystique, "It's not a gimmick," Jarjour said. "She's not thirsty."

Starrah's style

While social anxiety may keep her from award shows and meetings with label execs, her modesty and introvert's knack for listening have made her a favourite of today's superstars. "Starrah is the secret Dr Phil of the music industry," Jarjour said.

Starrah said she now looks at many of the artistes she writes for "like they're my family," but she's also a student of their sounds and personas. "As a fan, I know where I want their music to go," she said.

"I definitely creep" on social media, Starrah added, and said she reads gossip blogs for fodder. "Even though a lot of people say 'blogs aren't true,' what's said on the blogs still affects that person - period."

She recalled Rihanna gushing over the steely breakup jam 'Needed Me' - with its Instagrammable one-liners like "Didn't they tell you that I was a savage?" - which peaked at No 7 last year and went on to become the singer's longest-charting hit.

This year, having proven her Billboard viability, Starrah focused on expansion. Though she had previously specialised in the cross-section of club and critical favourites that became unexpectedly durable hits ('Pass Dat' by Jeremih, 'Body' by Dreezy), her work on tracks like Katy Perry's 'Swish Swish', Halsey's 'Now or Never' and Calvin Harris's 'Feels' were more naked appeals to pop dominance. And while not quite critically adored smashes, such songs may prove effective in Starrah's effort to stay unpredictable.
