Hosanna (A. R. Rahman song)

Hosanna (A. R. Rahman song) refers specifically to a popular song composed by A. R. Rahman for the 2010 Hindi film Ek Deewana Tha, which is a remake of the 2010 Tamil film Vinnaithaandi Varuvaayaa. Rahman also composed the music for the Tamil original, where the song "Hosanna" also features. The song is notable for its blend of Western and Indian musical elements and its use of the word "Hosanna," an interjection used in praise or adoration, derived from Hebrew.

The Hindi version, sung primarily by Leon D'Souza and Suzanne D'Mello, features lyrics penned by Javed Akhtar. The song depicts the blossoming romance between the film's lead characters. Its popularity stemmed from its catchy melody, Rahman's distinctive sound, and the relatability of its theme.

The Tamil version, also titled "Hosanna," is sung by Vijay Prakash, Suzanne D'Mello, and Blaaze. Its lyrics are by Thamarai. Both versions share the same musical composition by Rahman.

The song's use of the word "Hosanna" in the context of romantic love created some discussion, as the term is primarily associated with religious praise. However, within the film's narrative, its use conveys the protagonist's intense feelings of adoration and almost divine appreciation for the object of their affection.
