Hosanna (Ekk Deewana Tha)

There is an exuberance to this song that is almost architectural in its construction — it doesn't simply arrive at joy, it builds it, floor by floor, until the whole thing feels like it might not be able to contain itself. The percussion is anthemic, drawn from multiple traditions simultaneously, with handclaps and choir vocals creating a communal energy that feels both ancient and completely contemporary. AR Rahman's production here draws on devotional music — there are unmistakable echoes of church choir and qawwali intertwined — converting religious fervor into romantic ecstasy with characteristic irreverence. Vijay Prakash leads with a voice of considerable power, operatic in its range but never cold, and the female vocals weave through in counterpoint, creating a call-and-response that feels like a conversation between sky and earth. The song is essentially a love declaration made in the key of prayer, treating a person as something sacred enough to sing to with this much abandon. For the film, a cross-cultural romance, this became the title track's sonic embodiment — young, reckless, enormous. Culturally it sits at the intersection of Tamil and Hindi cinema during the early 2010s, when Rahman was interested in maximalism as spiritual exercise. This is music for headphones turned high, for the moment you decide to stop being careful about something, for runs and mornings and decisions you've already made.
