ILike is an iTunes plugin that helps you find new music you might like. After installing iLike, you'll see a new pane on the right side of iTunes. As you listen to music, the pane will display titles and artists you might like based on your musical tastes. The coolest thing about iLike is that it recommends both music on the iTunes music store AND free indy music. Within just a few minutes of using iLike I was able to find several free songs that I ... like.
You can also view what your friends have recently listened to, view each other's profiles, and send messages between each other.
