YouTube users have long been able to incorporate copyrighted music in the videos. But what will happen to the video once uploaded couldn't be known in advance. Whether a song will be blocked or monetized couldn't be known until the video is uploaded.
Now YouTube users get some transparency. Starting Monday, YouTube users can search the Audio Library to view usage restrictions, such as placement of advertisements and geographic limitations, of claimed songs in its catalog. This feature is enabled by YouTube's Copyright ID system that allows copyright owners to block the video, mute the audio or monetize the video that uses their song.
