It seems like right after the last big update it does this. I have premium so the only way I can use it is if I put on an album and play it from start to finish. If I do literally anything else it will play the first track, then it goes to the next one and the counter moves like it's playing but no sound. If I hit pause the counter moves back to 0, hit play and the song plays as normal. Then it ends, the next track does the same. It happens on playlists, radio stations, even if I play an album saved offline but try shuffling it. It's probably been around a month now.
