The Pandora app is one that can't go without mentioning. It is a fabulous free app that everyone should have on their Ipod and Ipad. You can select any artist's station you want and only their songs or thoes genre of songs will play. There is no selecting songs after one is finished and you are most likely going to enjoy every song that comes on that station if you like the artist you selected. It is an incredible music phenomenon and can be listened to while you are using any other app. It is so easy and convenient to use, especially if someone loves listening to musis and best of all it is free! What more can you ask for?
