It has been 5 stars for the past 10 years I've had it, up until about a week ago. The app will randomly close itself. When I have my phone closed while doing anything else the songs will start and stop randomly for a few minutes until self-closing the app, it sometimes will lower the volume to 0 making you think it's paused but you have to readjust the volume. Constantly pops up with "allow background usage" when it's already allowed. Its no longer worth the frustration or money.
