The lawsuit, filed in the Delhi High Court and reviewed by ET, alleges that Roposo is “blatantly, extensively and wilfully” infringing on T-Series’ copyrighted works.

The music label has sought a permanent injunction to stop Roposo from using its copyright material. When contacted, Roposo declined to comment.

“The app is infringing content under the user-generated content,” said T-Series president Neeraj Kalyan. “They are offering our music in their library and enticing users to upload our content in exchange for cash rewards. Their venture capitalists have not done due diligence, they are hand in glove.”

The lawsuit has also named Roposo investors Tiger Global and Bertelsmann.

T-Series has alleged that Roposo is actively providing and populating its app with the music label’s copyrighted works through the provision of a specially curated ‘Music Library’ and extracting songs from user devices and using such songs for commercial gain.

It has also alleged that Roposo is removing the rights management information pertaining to its copyrighted songs in the ‘Music Library’ and knowingly distributing, broadcasting and communicating to the public infringing copies.

T-Series recently signed a licence agreement with regional language social media platform ShareChat. It already has a similar deal with Facebook and Instagram. Last year, T-Series had filed a copyright infringement case against ShareChat.
