So in iTunes 10 you can now play music from an attached iPod. Basically if your friend has music he/she wants to hear at your party but it is only on his/her iPod, you can now attach it and play it. Before you would need third-party software like Senuti (which I still like) to do this.

Music control via album artwork. Say what? OK, really easy. Next time you have a song playing, click on the album artwork on the left bottom to increase the size and then mouse over. This is pretty cool, like when playing iTunes DJ or anything like that (shuffle etc) and you want to have iTunes minimized and the artwork up on screen with controls enabled.
