iTunes Playlists are Empty

Early Tuesday morning I had an issue with my songs on my iPhone appearing without their artwork. So I removed all the songs from my phone and then resynced and added them back. The problem is now after doing that all of my playlists appear on my PC as empty and are no longer on my iPhone. I've seen the option of going to the Previous iTunes Libraries folder and choosing a set date and going back, the issue is my last date of this year is in July and that would ruin four months of purchases and uploads that I've done since then. Is there another way to restore my empty playlists without having to go back to July? When I try a backup option, the dates are all from 2014 unfortunately. SOS
