While Vishal Shekhar claim to have remixed this song Bachna E Hasino because they love Pancham too much I simply see this as a way to cover up mediocrity.
Better way of showing bhakti would be to compose an original tune by VS as good as this one and then dedicate that to RDB..!
Most of their (VS) output to my knowledge has been in the fast music,
item songs and club-mix sections. Unlike SEL or ARR - they have not
explored the spectrum of folk, classical, pop, filmi, type of
numbers. Hence when this duo pays tribute and
mention how much devotion and inspiration they have and get. I take
all that with a pinch of salt. Why remix a song when the original is so good...!!
