If you missed the premiere you can play or purchase the song (a duet with Drake) on Tidal - the streaming service Rihanna reportedly has a 3% stake in [Update: It's now on iTunes, too, where it's billed as having "a love-at-first-listen hook fuelled by Auto-tune magic"].
But if you can't be bothered to sign up for that, here's a blow by blow account of the first track from the long-delayed #ANTi album.
0:00 We open with a supine bassline. It's sparse. It's slinky. It's a mid-tempo Rihannabanger.
0:10 Heeeere's Rihanna! "Work, work, work, work, work, work," she sings.
0:12 Furthermore, she adds: "I’mma work, work, work, work, work, work."
0:15 "You see me do me dirt, dirt, dirt, dirt, dirt, dirt," Rihanna continues.
0:17 In conclusion, she notes: "There’s somethin’ bout that work, work, work, work, work work."
0:19 So far, it's a lyrical masterpiece.
0:23 At this point Rihanna starts to sound a little woozy. Maybe she needs a rest after those first 13 seconds of vocal effort.
0:34 Great lyric >>> "Nobody touch me in the righteous / Nobody text me in a crisis."
0:46 Amazing flute motif arrives.
0:53 Rihanna pronounces "foundation" as "fownd-ay-she-yawn". Love that Bajan accent.
1:04 Oh, the "work, work, work" bit is the chorus.
1:22 But now she’s just singing "nah, nah, nah". It's not like the lyrics were difficult to remember in the first place.
1:31 Muted steel drums prove Rihanna is "on trend" with the “tropical house” sound.
2:07 Rihanna has become so drowsy that "work, work, work" is being pronounced "weh, weh, weh". The poor lamb is exhausted. Someone get her a blanket.
2:11 Here's Drake. He sounds like Drake (ie monotonous).
2:31 Nice harmonies here.
2:47 Guitar solo!
2:48 Only joking.
2:39 Although any kind of musical development would be welcome at this point.
3:01 Repeat chorus to fade.
3:26 I'm going to listen to this again.
Overall, I'm giving it an early 6/10 (ratings out of 10 may go up as well as down). It's a confident, if slight, scene-setter for the album - but one I expect will be eclipsed by the second single.
