Yuvan Shankar Raja has begun the final mixing for Anjaan’s music.. The soundtrack will be launched on July 22, by Kamal Haasan, in a grand event in Chennai. The music composer will finish the mixing work in a few days, and handover the master copy of the audio soon, says a source close to the film. The Bang Bang song in the teaser has become very popular and is the ringtone of choice for many a Suriya fan now. A lot is riding on the music for Anjaan, as the duo had teamed up earlier to give hits in Sandakozhi, Paiyya and Vettai.
