I have Premium on a Samsung Galaxy S4. When I play music continuously in any category on my mobile device, the first song I select plays just fine with sound. After that song plays, it moves on to the next song and looks as though it is playing (the time is going by in the song), but no sound comes out for the second song, third song, and so on. I've tried uninstalling and reinstalling the application, but this has proven unsuccessful. I need help figuring out the problem.
