Professional reviews
Indiaglitz:"The brilliant composer in A R Rahman has woven a lovable song around the word Hosanna (considered auspicious by Christians). With rap interludes in between by Blaaze, the song sticks to hearts instantly. Anantha Sreeram's lyrics describes the joy in the heart and soul of a guy who comes across his beloved. A soulful romantic number, the song with Suzanne chipping in with her best is the USP of the album." Behindwoods:"Christian tradition defines Hosanna as the cry of adoration of the Messiahship of Jesus on his entry into Jerusalem’. Rahman has boldly adopted it to express the joy that erupts in the heart of the hero when his soul mate walks into his life. This lovely number, a mix of a few genres, is richly layered with violin, flute and many other instruments and conceived very differently too. We hear bits of Mohanam and Natabairavi notes all along. Could rock the charts." Lordofthewebs:"This has to be the most popular song of the album. Amazing music, singing and lyrics combine to create this masterpiece that is bound to be wildly popular with the crowd. What begins as a melody with soothing music and soulful female chorus parts transitions beautifully into rap and then back to melody. Vijay Prakash has beautifully captured the mood of the song . Suzanne, with her excellent singing culminating in a mesmerizing humming has made the song better, if that is even possible. Blaaze is good with what he does, as usual." Radioandmusic:"This track is bound to have a mass appeal with its contemporary arrangements and rap portions rendered by Blaaze. Vijay Prakash is at his best and the track starts on a melodious note with Prakash, enters the rap- hip hop mode with Blaaze and Prakash again brings back the melody bit. Suzzane D’Mello’s humming in the background makes the song even more likable." Rediff:"On a half romantic, half mournful note, with a flute interlude begins possibly the most publicized number of the album: Hosanna by Blaaze, Vijay Prakash and Suzanne. The musical arrangement somehow takes you right back to the early days of ARR until you realize which number the refrain, Hosanna, bears a striking resemblance to: Only Time, by Enya. The rap segment closely follows the tune as well; the lyrics celebrate the lover pining away for his beloved until his world shrinks to just her. There's no denying that it's romantic what with church bells pealing, complicated violin arrangements and a chorus which all reach a crescendo in the finale. It's a pleasant listen but still seems inspired." Kollynews:"This one is the pick of the lot for me. Nice rap number. With amazing humming and very smart singing. Tamil lyrics are too good. The componsition and the use of guitar is at a different league. The lyrics suggest that the picturization should be interesting."
