Ajay Devgn raps with Yashraj Mukhate in Runway 34 promo song

Ajay Devgn has collaborated with influencer-music producer Yashraj Mukhate for a track. Meant as a promotional number for Runway 34, the music video combines scenes from the film with Ajay and Yash's jam session. Ajay raps a few lines in the later half of the video.   

Written by lyricist Rajeakshay Shinde, the track is titled 'Jalaya Toh Nahin Na', after Ajay's catch-phrase in the film. "This was sooo much fun!! @ajaydevgn sir doing a rap section for the first time in a track that I made. Isn't that insane??" Yashraj tweeted.

Runway 34 stars Ajay with Amitabh Bachchan and Rakul Preet Singh. The film is Ajay's third directorial attempt. It is releasing in theatres on April 29.
