Singer Sonu Nigam is up in arms against music giant T-Series head honcho Bhushan Kumar. After Sushant Singh Rajput’s death, Sonu had said that there could be some Sushant’s waiting in the wings even in the music industry. It was only about time that such oppressed singers or composers either spoke up about their hardships or the news of their suicide could shake up the fraternity further. To this, Bhushan Kumar suddenly released a document along with support from some singers. The document termed Sonu’s claims as false. Not the one to take this lying down, the crooner has now come out harder than ever blaming Bhushan for creating the mess and that he has “messed with wrong person”. Sonu has also said that he will take Bhushan Kumar to task very soon.
