Up Next is a new type of task app that not only lets you enter todo items, but helps you decide when it's best to complete them. By using your location and the current time of day, Up Next looks at context to help you save time and complete your day in a more efficient manner.
While creating playlists has always worked in the past, it has always left something to be desired when it comes to adding music or tweaking content quickly. iTunes 11 aims to solve this problem with its all new Up Next feature. The idea is that you can add songs when you think of them quickly and they'll be put in an easy to access queue in iTunes that you can edit, clear, and add to whenever and as often as you'd like.
