Retro beats have certainly had a great comeback this year with many big banner movies having at least one popular track from the retro years albeit with contemporary touch ups to woo the current generation.

So the question is has Bollywood been obsessed with the retro beats in 2010? Well the fact is that many films released during the year have the most popular retro numbers which indeed have added to their popularity quotient amongst the audiences.

Movies like Once Upon A Time In Mumbai, with the Parda number which had a mix of music composer R.D Burman's two of the greatest hits Duniya Mein and Monika sung by Sunidhi Chauhan and Rana Mazumder, then the flick Houseful, which had the popular retro number Apni toh jaise taise from the 1981 flick Laawaris, or movie Golmaal 3 which had the Disco Dancer and Yaad Aa Raha Hai numbers from the movie Disco Dancer were all amongst the hit numbers of this year that had the younger generation humming to these retro numbers with equal enthusiasm as the older generation.

Now why is it that film makers are getting attracted to these retro numbers that have already seen an immense popularity during the retro years? Some reports suggests that it is due to the fact that since these numbers are already hits and are already registered in the memories of the people it becomes easier to make the audiences identify with these songs.

Others feel that since music composers are quite burdened with a lot of work there is hardly any time to invent new snazzy tunes everyday so going retro is a fast and easy way out to churn out popular numbers which has the potential of attracting audiences by the dozen.

However reports are that no matter how popular these retro numbers might be, but for commercial value as in terms of ring tones and down loads it is the original new numbers that are audience's picks!
