There is no doubt that his achievements are phenomenal with no formal training in classical music and it is not nice to write negative things after a great personality's demise. But people like me soaked in the melody of the 60s,70s and late 50s of Rafi saheb,Kishoreda,Mannada,Hemantda,Talatji and Mahendra Kapoor cant say he was exceptional in Hindi movies. We always made fun of his typical Tamil style and accent though he was better than Yesudas in his accent. My apologies to all his fans who will be hurt by my comments
