Let's say you published a video with a copyrighted song and you've already made $200k out of that video and the money is already in your bank account. Will the copyright holder ask you to pay the money back? Here's an example: Alan Walker - Spectre NoCopyrightSounds published Alan Walker - Spectre back in 2015 when Alan Walker was not famous. The song has eventually broken the 100 Million views barrier on YT. He then signed with Sony Music and re-released the song in 2017. The song is now copyrighted. Will NoCopyrightSounds have to pay back Sony Music all the money they've already made with that song in the time interval of 2 years?
