Is Youtube really better at identifying the music? For one video my father posted we got a complaint that some company owned the song for the part where my sister was playing the piano and singing. It offered the option of muting it or allowing ads with the money going to the company. What it didn't say was what song specifically it thought the video had. So though they offered the option to contest it there was no way for us to do that without this information. The lyrics were something my sister had written herself, so it was very likely that it was a false match. It obviously had a recording of what they thought matched or it couldn't have made the comparison. But without allowing me access to that recording there is no way to know if their algorithm is any good.
