Restore New iPhone from back up - Music Download
I recently changed carries and restored the iPhone 6 I received from my most recent backup. After the restore was complete I noticed that only certain (very, very few) of my songs were downloaded back on to my phone. The others were listed but with the icon to download each individually from iCloud. My question is that while I am pretty certain there has to be a way to download in bulk all my songs from iCloud at once or at the very least download each artists albums instead of having to download each of the hundreds of songs I have individually, I just do not know where to this or how?
Thanks in advance.
iPhone 6, iOS 8.3
