It's an opera with various songs. For four of these songs, content ID reported a melody match with a composition. Keep in mind that compositions and performances have separate copyrights and often separate owners! Compositions have to be registered separately in content ID. https://support.google.com/youtube/answer/2822002?hl=en https://support.google.com/youtube/answer/2822002?hl=en What happened was that each song was correctly identified by its melody and matched with an entry in the composition database, even though the compositions are clearly public domain.
