Q: Help! My whole iTunes library is gone after doing a restore on my iPhone 6s

Hi mccall15,

I understand that you are not seeing your entire iTunes library on your computer. Let's see if we can get that back for you. 

This is something you can fix by restoring the previous iTunes library database file. Take a look at the article below to walk you through the location and the specific steps to replace this. Once that is done, open up iTunes and you will be able to see your entire library.
