Arijit Singh

Before "Tum Hi Ho" made him a household name in 2013, Arijit Singh was working behind the scenes as Pritam's assistant, which explains why his songwriting instincts feel more composer than singer sometimes. He's been Spotify India's most-streamed artist for seven years running and now matches Kishore Kumar's record for Filmfare wins. If Bollywood needs a song about heartbreak these days, it's probably his.
