Twelve days before Daayra hits theatres, we finally know who's singing its one song. B Praak has lent his voice to the track, according to Pinkvilla, which cited industry sources for the news. Filmfare has since corroborated the report.

The pairing itself is the story here. Gulzar has written the lyrics, Amit Trivedi has composed the music, and B Praak — known for Mitti and Ranjha, sings it. Three names who rarely share a credit line, all landing on a single track for a film that otherwise has none.

Meghna Gulzar announced at a press event a few days ago that Daayra would carry just one song. Trivedi confirmed soon after that he'd composed it. The singer's identity was the last piece missing, and now it's in place.

Why one song matters here

Meghna doesn't reach for music often. When she does, it tends to stay with you. Dilbaro in Raazi did that. So did the lone track running through Talvar. Her films use songs the way a good editor uses a cut. Sparingly, and only when the scene actually needs it. A single song in Daayra, then, isn't a marketing shortcut. It's a choice that fits how she's always worked.

Which makes the secrecy around this one interesting. The makers haven't released it, haven't teased a lyric video, haven't said a word about where in the film it lands. For a crime thriller built around two cops on opposite sides of a justice debate, Kareena Kapoor Khan and Prithviraj Sukumaran play those officers. A song that arrives without warning could do real work. Or it could just be a pause button between interrogation scenes. We don't know yet.

What we do know is that the film's trailer has already done its job. It's sitting at No. 1 on IMDb's most-anticipated list, per Filmfare, and clips from the recent event have been doing rounds online. A lot of that traffic is simple curiosity: Kareena and Prithviraj haven't shared a screen before, and seeing both of them in uniform, arguing procedure and ethics, is new territory for each.

Daayra is produced by Junglee Pictures and Pen Studios, distributed by Pen Marudhar, and releases in cinemas on September 18. That leaves less than two weeks for the song to surface, assuming the makers decide to release it before the film rather than let audiences discover it in the hall. Given how tightly Meghna has held every other detail so far, don't bet on an early drop.
