[gentoo-user] OT: Anybody know of a 'Genius' type service or site for TV shows/Movies/Music that is not owned by Apple?

By 'Genius' type service, I'm referring to Apple's Genius service that 
helps you find new music that you might like based on your current 
likes... ie, you tell it the Artists/songs you like, and it tells you 
things that are similar.

It is a very interesting way to find new music/artists that you 
otherwise may never find out about, and I'm hoping to find a service 
(paid or free) that does the same thing for TV, movies, online video 
content.

Thanks...
