I'm coming close to completion on a VR Home map and would like to include musical performances from early in the previous century. I know these recording are still copyrighted until the 1st of January 2022 when they will become public domain as will all recorded performances before the early 1920's. Is there any problem submitting the map before or after this occurs containing these audio files? This is really obscure music that no one listens to today. I was just wondering if there was some kind of filter to remove questionable audio files.
