5 August. The soundtrack has topped the Indian charts too. The first five positions was defended by Enthiran songs for more than three months. "Kadhal Anukkal" topped the charts for more than eight weeks. The Hindi version, "Pagal Anukan", peaked at #4 position in the weekly charts. The audio is said to have created history and have registered a record breaking sale in the Indian audio market. Critical response Tamil version The soundtrack also received positive critical responses. The Hindu commented on the album that "With its blend of melody, trance and rhythm, Enthiran – The Robot sounds like a winner". Chennai online stated that "The entire album gives an upbeat electro sense and wings to our imaginations. The music is convinced to grow on you, if not an instant hit." A review by Music Aloud said, "While the soundtrack of Enthiran has enough fodder to delight a connoisseur, it remains to be seen how much its sophistication will appeal to the masses, who are after all Rajinikanth's primary target." Behindwoods reviewed the music saying, "Yes, it exasperates you when you listen for the first time. But as you listen again, you realize that though Rahman gives this album a crisp metallic touch in keeping with the theme of the story, he still remains faithful to his Carnatic roots in a touching way. Watch how cleverly he varies the feel of the normal duets and robo-based duets. The lyrics are interesting too. If the listener shakes off his conditioned thinking while listening to this album, he is in for a treat." Pavithra Srinivasan of Rediff commented that, "Enthiran is, in fact, a perfect superstar album. Where the collection does manage to veer from the usual, Rahman has managed to add his own quirky, creative notes to the songs." Hindi version The Hindi version received notably mixed responses, with most of the reviewers criticising Swanand Kirkire's lyrics. Bollywood Hungama rated the album 1.5 out of 5 saying, "Robot disappoints. While Rahman himself hasn't come up with anything exceptional, something which is expected from him film after film; it's the lyrics that are chief culprit here. It is clear that a lot has been lost in translation here, literally so, as the song dubbing Tamil to Hindi just doesn't work here." Glamsham published a positive review saying, "Robot is stylishly packed sci-fi musical entertainer, exuding out multifaceted classy acts from the maestro.
