DNA: This could start a new trend in film music. The music of Karan Johar’s latest movie Kabhi Alvida Na Kehna (KANK) was first released in the audio CD format, and they would be available in cassettes only a few days later. Sanujeet Bhujabal, general manager, marketing, Sony BMG Music Entertainment India Pvt Ltd, who released the music, said the idea was to “cash in on the growing consumption of music in the digital format”. The audio CDs have been priced at Rs 99 a disc. This will make hardcore music buffs dish out more money (against Rs 55 for a cassette) since they buy in the initial week. The other industry players are also watching the trend closely.
