Composed by Shankar Ehsaan Loy and sung by Shivam Mahadevan and Jonita Gandhi, Sajan Bin is a fusion of Indian music and EDM with catchy lyrics by Divyanshu Malhotra.

Radhe, a music prodigy in the classical tradition, meets Tamanna, a viral YouTube pop sensation, who comes from a world diametrically opposed to his.

Radhe's interaction with Tamanna jeopardises his musical dream, so that he has to prove himself to his mentor and grandfather, Panditji.

Radhe begins to sing with Tamanna for financial reasons, but love and attraction grow between the young couple as they work on their first song together.

Personal and musical stress starts to show as Radhe feverishly juggles the simultaneous and clashing demands of Tamanna and Panditji.

Radhe gets a shocking glimpse into the inner life of his grandfather, even as he struggles to navigate a tense music video shoot with Tamanna.

Radhe starts training under Panditji to sing against his estranged uncle Digvijay, while his first song with Tamanna releases and is an instant hit.

Radhe takes on new gigs to help repay his father's loan, which puts a strain on his increasingly fraught relationships with both Tamanna and Panditji.

Radhe teaches Tamanna to sing live for a last shot at her dream of collaborating with an international pop star, while his own training with Panditji receives an enormous setback.

Radhe is utterly broken and on the verge of giving up as he loses both Tamanna and Panditji, but his soft-spoken mother rises to save the day.

Joy, sorrow and adrenaline charge through the final episode as Radhe and Digvijay sing off against each other in a fierce battle for the Rathod family's musical future.
