Singer-businesswoman Ananya Birla, daughter of Aditya Birla Group's billionaire Chairman Kumar Mangalam Birla, is quitting music. "This has been the hardest decision...I've reached a stage where balancing both the businesses I run and am building + music is becoming near impossible," the 29-year-old posted on social media. "It's time I focus all my energies to the business world," she added.
