Today, my phone battery died. Once I managed to charge it up for awhile, I restarted the phone and noticed that all of the songs that were in my playlists (including one that's 500+ songs) have disappeared from the playlists. They're still on the SD card and still show up in Poweramp, but my playlists have all been cleared of any music. This is the first time this has happened in around 9 months of using Poweramp. My phone battery has died a handful of other times and I've had no problem like this.
Apologies if this has come up in other older posts, but I thought I'd submit it so it's still getting attention. It's pretty frustrating, since playlists are a major part of the way that I listen to music.
