ipod touch itunes help needed.
I purchased an album of ITunes the other day on my ipod touch and downloaded it. After a couple of hours of listening to it I got a notification for the latest update. After install my latest purchase disappeared from my music. I tried going to the iTunes app and redownloading it but when I clicked on the cload symbol it just said already downloaded. No problem I thought so I loaded iTunes on my Mac and tried to transfer it that way. I get the copying to my ipod come up for the correct amount of songs but it still doesn't show at all on my ipod. Any help would be appreciated. Thank you.
Btw I can still play the album in iTunes on my mac fine.
iPod touch (5th generation), iOS 8.3
