Genius Playlists’

So I’ve recently begun to use the Genius playlists’ on itunes and I must say, they are pretty awesome!  I can get in a rut from time to time, listening to the same old thing all the time, this helps. Plus, you know how your mood determines the type of music you listen too? For example: sometimes I am in a real chill mood and want to listen to chill music. Well, now instead of hunting though my library to find all the chill music and making a new playlist, itunes does it for me! This I like! Laziness or time efficient? I think the latter!
