Please help with this:

Hello!
I started cooperation with a Russian company that releases music on digital platforms (iTunes, Google Play, Spotify and others).

The company is ready to provide the scope of rights and fragments of the phonogram for sale on stocks. Since the market is broad enough for them, they can upload music files through their account.

Tell me, is it possible and what rights will I have to grant?

These tracks are released to digital platforms through the belive aggregator

Can’t say much about the subject, but check out this forum, maybe it will help.
