When I use Spotify offline with headphones, sometimes (read: often), it starts skipping ten second bits in the songs I want to listen to. It plays one second, skips ten, plays one, skips ten. It doesn't help turning Spotify off and on a again, turning the phone off and on again, it still keeps skipping in my songs! Why is this happening? I have not experienced this when playing online, as I almost exclusively listen offline.
