I did a score of a song that was removed because of a Copyright Infringement. I honestly don't know how copyright laws work on Musescore (Or in general). If i were to upload a cover of a song, do I have to get permission from the owners of said song before i upload to Musescore? Obviously there are a lot of covers on Musescore, and i honestly don't know how they're able to upload all of them without one really getting a copyright infringement. Additional information on Copyright laws and Copyright Infringement would be much appreciated.
