And now, there’s her hugely anticipated single titled “Work.” It’s about working for a paycheck no matter what else is going on in your life. It is also, of course, designed to get her that paycheck. You might call the way it goes about attaining this goal brazen for anyone else but Rihanna: Tempting accusations of boringness, hackiness, and crimes against art, the song offers a hook that practically parodies pop’s love of repetition—and then repeats it, a lot. But there’s something fascinating about the tune, something that elevates it beyond ringtone status. It doesn’t really go anywhere. It approximates what work feels like.

The producer Boi-1da’s bright, bubbly beat creates a see-sawing sensation out of a few sounds. A keyboard ping anchors the downbeat and then climbs up, up, down, down, returning to its starting point. Electronic notes on the low end burble out a more asymmetrical pattern recalling reggae, but they too have the general shape of ascending and descending. The percussion is subtle, rendered with a skittering sound that recalls the shaking of a kettle. When Rihanna’s voice comes in, so do some signifiers of ’80s and ’90s dance and rap: digital handclaps, distorted shouting. It all adds up to the feeling of a lot of bustling in one spot—activity, but not necessarily movement.

Rihanna’s hook conjures a different kind of monotony. After a few quick notes in yet another up-and-back pattern, she gets stuck, like a needle in a groove, for “work work work work work.” There’s no stopping this getting in your head. “Work” becomes “dirt” becomes “love” becomes “turn,” but the modulations don’t matter—Rihanna has found her next great nonsense syllable, another “ooh na na” or “ella ella eh.” Her singing in the verses, where she dresses down some guy who isn’t meeting her expectations, is actually rather pretty. I’ve seen a lot of commenters say she’s copying the mumbling trend that’s taken hold among younger pop vocalists like Ariana Grande, but the truth is that Rihanna helped popularize the notion of liquifying words in the name of catchiness.

As for Drake’s verse, it strikes me as pretty terrible—the disappointed lounge singer schtick from “Hotline Bling,” but without the silken melody or sense of surprise. “If you had a twin I would still choose you” is the only real attempt at a memorable line. Whatever. Drake being as popular as he is right now will be yet another incentive for radio playlist makers to keep this song in rotation, possibly giving it the activating energy needed to become a hit.

And to be sure, it will need a good deal of exposure to reach the success levels of Rihanna’s previous smashes. The song’s undeniably catchy, but it also has a strangely unfinished quality. To me, though, that’s its charm. The verses, choruses, and bridge mostly bleed into each other, forgoing soft-to-loud explosions or exciting rhythmic changes. Boi-1da does create some sense of escalation—another drum beat for the second chorus, flashes of flutes, autotuned harmonies, and far-off piano. But the shifts are subtle and fleeting. Unlike a lot of radio pop, “Work” is about small modulations, a singer and a producer and a rapper plugging along as we all must do. At the end, the song makes the unfashionable move of simply fading out. Rihanna put in her three and a half minutes of work; now pay her what you owe her.
