Ok so I'm uploading a CD to YouTube, it's a CD full of Dubstep remixes. The first track is a Rihanna - Rude Boy remix. I have edited the ID3 tags using 'ID3 Editor' on the Mac, I've also not mentioned Rihanna anywhere in the title, desc., tags etc. It's labeled as "Dubstep CD 1 - Track 1". Every time I upload I get a copyright error from UMG (Universal Music) and when I go to the video it says "Buy iTunes" and it has the track name Rihanna - Rude Boy next to it. I ensured the file was renamed aswell before I uploaded. How does it know this? And how can I get around it?
