I had to restore my iPhone because the iPhones store app wouldn't show up in any of my apps. Now that I restored it I have to download?

All of my music again. When I click on the clouds to download it the spinning circles will come up and act like its gonna download for a little bit but then just stops and goes back to the clouds. None of my music will download. And my phones acting up now. Does anyone know how to fix this?

Due to resetting the iphone and still issues you need put into dfu mode. Hold the power button and homebutton in together for 15 seconds, then release the power button only, the screen will have chimed and flash restore and now should be black as if powered off, release the home button, ( uses original factory bootloader was shipped with / different than normal recovery / restore option ) open pc/mac open itunes, follow the prompts and will download and then install a fresh system. Be patient as when reboots after… Just wait as not finished and will continue… Pc will show welcome to your new iphone but the iphone if look will still be loading… Sync your music etc, sign into your iphone and if prefer select a back up… Make sure even though will be plugged in that the power is above 60% on the battery minimum before starting!
