I have accidentally deleted a music album off my iPhone and now it doesn't show in my purchased music either. I can still find the album when i search for it on iTunes. However, when i tap the album, all i get is a non-working purchased button in the place where the price button should be. Does anyone have an idea on how i could get the album to redownload again? I only use my iPhone 6 plus and have no pc, so ideas will have to be non-pc related please. Thanks in advance.
