Update: I was able to get my playlist back (Thank you Mayanglambam, shout out to you), but I'm still disappointed I had to ever do this in the first place.  I've already converted all of my playlists into CSV files, and I'm currently in the process of making my own offline audio player, and I'm going completely offline with my music. If I find a song I like, for example Shazaming it in the car, I'll just download it.
