iTunes 10 has the following new features
1. iTunes gets a new icon
2. iTunes got Ping – which allows you to share your friends what you’re listening to and even share information on concerts and events.
The new social network built into to iTunes is called Ping. You’ll be able to see what your friends are listening to, make recommendations and is going to be used for “social music discovery”. You’ll be able to control who follows you by setting up a “Circle of Friends” so you control who follows you, or you can allow anyone to follow you.
Ping is available now to all iTunes users and allows for multiple forms of sharing including image and link posting.
