How does yahoo! music actually KNOW which songs you like??

Question

I heard that yahoo! music recommends new songs that you might like just by watching any music videos… even if they’re by a different band/genre. Is this for real?

Answer 1

it sees what types of music you like and recommends some popular songs from the genre,

Answer 2

The entire thing is done with clever software and a lot of information from which the software can choose from same genre or a sub-genre or from music listened to, which receives high ratings, from other users who are fans of an artist or choose from music with many similar musical qualities or features as the artists you tend to choose.  The good part is, as you rate more music and watch music videos the software has more information to choose more accurately the music you will like.
