"'Munni...'and 'Sheila...' have their own space and have already done what they had to do. We are looking forward to 'Dum Maro Dum' becoming one of the chartbusters. If we can do that, I think then we are kind of sorted, " Bosco told.
"I think it should be one of the biggest after 'Darling...' that has made a lot of news. I hope the audiences kind of love the way it is done, " he added.
Bosco made the steps tougher for Deepika, who is appearing only in the special video shot for the promotion of Rohan Sippy's crime thriller that stars Abhishek Bachchan and Bipasha Basu.
Talking about Deepika, Bosco said: "The minute we got to know it is Deepika, we pushed the envelope and made the dancing little tougher. What is really positive is that Deepika learnt the steps very gracefully and executed them very well."
The title "Dum maro dum" reminds one of the iconic song from the 1971 classic "Hare Rama Hare Krishna", which was picturised on Zeenat Aman. The film was acted in and directed by Dev Anand.
Bosco claims the new track is fresh and least comparable with the old one.
"The track is very new. The whole treatment is quite new and then we got going with the idea. We didn't want to compare it with the old one because the old one is so huge, you know. We wanted an identity for our own song so made a completely different sounding track and gave a completely different look, " said Bosco.
"You cannot overshadow something, which is eternal. You cannot compare and you cannot say this (new one) is better. They (classics) are priceless in their own form and it's completely different treatment that we have given to 'Dum Maro Dum'. That was chilled out, it's more dance based, " he added.
"Dum Maro Dum" is scheduled to release worldwide April 22.
