iOS 9

[user-removed]

whenever i add songs to my music on my iphone, it doesn't update the songs on my ipad without me having to go in and manually adding the same songs on my ipad. is there anyway to get them to update at the same time? the same thing happens when i delete music from my iphone app; my ipad doesn't delete the songs so i have to repeat the whole process of deleting the music manaually on two seperate devices.
