Music composer Rishi Chanda has claimed that the hook line of 'Caller Tune', a song from Vashu Bhagnani's film, 'Humshakals', is very similar to the song, 'Soniye Tu Janiye Naa', that he composed for the Bangla film, 'Khokhababu'. Chanda says, "I will send a letter to Fox Star Studios and Vashu Bhagnani as the tunes are very similar."
