My friend asked me if he could record a cover of a song that I put on SoundCloud called Gratitude (License: All Rights Reserved).
What legal rights does my friend have? Does he need my permission?
What benefits, compensations, acknowledgements, etc. am I legally entitled to? Does my friend have to pay me mechanical royalties if, e.g., he publishes his version of the song to SoundCloud such that anyone can listen to it for free?
