The post instantly resonated with fans, generating a wave of birthday wishes and excitement around the track. The hashtag #WOWItsVarunDay trended as the song dropped, amplifying the film's pre-release buzz significantly.

Track Details: Artists, Composers, and Sound

'WOW' is a high-octane, foot-tapping dance number featuring vocals by Harrdy Sandhu and Kiran Bajwa. The track has been composed by Tanishk Bagchi, Rony Ajnali, and Gill Machhrai, with lyrics penned by Rony Ajnali and Gill Machhrai.

The song is crafted to deliver a sound that is fresh, punchy, and instantly addictive — tailored for the party-anthem circuit. Its contemporary production style reflects the current trend of big-beat Bollywood numbers designed to dominate playlists and wedding dance floors alike.

Artists Speak: What Makes 'WOW' Stand Out

Singer Harrdy Sandhu expressed his enthusiasm about the track, stating: "From the first listen, WOW had that spark. It's high on energy and super addictive — the kind of song you don't just hear, you feel. Recording this with the bunch of amazing creative collaborators was an absolute blast."

Singer Kiran Bajwa highlighted the song's playful and vibrant energy, adding: "It's bold, catchy, and perfect for anyone who just wants to let loose and have fun."

Composer Tanishk Bagchi explained the creative vision behind the track: "With WOW, the idea was to keep it contemporary, punchy, and irresistibly catchy. It's designed to make you move — simple as that. Every artist involved added their own personal touch which elevated my vision for this song."

Lyricist and composer Gill Machhrai said: "We wanted to create something that clicks instantly while still having longevity, and WOW just delivers that."

Co-lyricist Rony Ajnali added: "The lyrics are fun, easy, and instantly memorable. Every line and beat is crafted to build the song's energy and make it a go-to party anthem. The end result is absolute vibe."

Tips Music's Kumar Taurani on the Film's Musical Vision

Kumar Taurani of Tips Music, the label backing the film's music, spoke about the collaborative magic behind the track. He noted: "What we had here was the right combination from the start. Harrdy, Tanishq, Kiran, Rony, and Gill each bring something distinct, and together they give this track a range that's hard to manufacture."

Taurani also acknowledged the visual appeal of the track, adding: "Add Varun, Mrunal, and Pooja to the visual and it just completes the picture." This confirms that alongside Varun Dhawan, actresses Mrunal Thakur and Pooja Hegde feature in the song's visuals.

Film Release and Broader Context

'Hai Jawani Toh Ishq Hona' is scheduled to release in cinemas on 22nd May 2026. The film marks a significant commercial outing for Varun Dhawan, who has been on a strategic comeback trail following the mixed reception to some of his recent projects.

The decision to launch a high-energy song on his birthday is a calculated marketing move — combining personal celebration with promotional momentum to maximise organic reach and fan engagement ahead of the film's release. With summer 2026 shaping up as a competitive box office season, building early music buzz is a proven strategy to anchor audience anticipation.

As the May 22, 2026 release date approaches, fans can expect more tracks, trailers, and promotional events to follow in the coming weeks.
