Indy, is a streaming music “discovery program”—
Indy uses an advanced collaborative filtering system to predict what kind of music you’ll enjoy hearing. As you rate songs, Indy finds out what you do and don’t like. It compares your preferences with the ratings of all the other Indy users. For example, if you rate a song highly, and another user also likes the same song, Indy guesses that you’d probably like other music that they enjoyed. As you rate more songs, Indy will gets better and better at picking songs that you’ll really enjoy.
