What gets posted on You Tube is the business of You Tube and not our business.
I think that, um, the content of the hyperlink does indeed matter in the end. Elsewise posting recent CDs uploaded to The Pirate Bay or Rutracker or some other torrent site would be entirely kosher. :P
Youtube's a strange case, though, because it's not explicitly a site for pirates (it has a takedown mechanism and a way to report videos) and it does have a "content ID" system that tries to compensate musicians for the playback, even if they did not upload the work. A lot of musicians are unhappy at Youtube's meager streaming pay rate though (plenty of articles about that).
I think the risk to this forum is non-existent. If the original record companies wanted to take down the copyrighted content, they'd report it to Youtube directly, not to the small sites linking to it. So it's more of an ethical question in the end.
