Megastar Amitabh Bachchan says the process of recording songs has become more complicated now.

Big B, who has recorded a song titled Badumba for his upcoming film 102 Not Out, wrote on his blog: "The entire concept of recording songs has changed. From being complicated several years ago, it is now even more complicated as the world moves towards modern technology, an inevitability, our sense of recreation preservation and exploitation has become even more complex."

The film also stars veteran actor Rishi Kapoor. 

Amitabh's character will be seen as a 102-year-old father to a 75-year-old character of Rishi in the film, directed by Umesh Shukla. 

Billed as a most unusual father-and-son love story, the film is based on playwright Saumya Joshi's well-known Gujarati play by the same name.

The film will release on May 4.
