YouTube Identifies Soundtracks, Creates Auto Playlists?

I was watching this mega-awesome video and noticed that YouTube identified the artist on the soundtrack (Hybrid) and linked the artist's name to a separate page containing more artist details including other tracks, a playlist button, upcoming events, and an info blurb.There's also an affiliate "Buy" link placeholder under the artist's name, but it was left empty. This seems to be a part of YouTube's Content ID program, but I haven't it in this type of action before.

Bonus track: one hacker explores how Content ID works.
