I have an LG optimus phone and Cricket is my carrier. I'm having problems with my Music Player (not Google music). Another thread had problems with their songs disappearing, but the names of the playlists still being intact. I have the OPPOSITE problem. I will create a playlist of a handful of songs, and then the playlist will work a couple times, and then disappear out of nowhere. The songs that are in the playlist are still on the phone, but the playlist itself just disappears. Any idea of a possible way to fix this or what might be going on?
