I have a Sony Xperia Z, Premium used to work perfectly and love/loved the service until I think an update changed that. Or it could be my phone. Made a new playlist on a new account hoping to reslove the fact I play a song and it cuts out 5 seconds in and I can't download any playlists. Tells me to go online and download then changes to turn on 2g/3g to downlaod a couple of seconds later. When i do it goes up percentage wise on the download but when i go to listen same problem- cutting out. I have very efficient 4G so don't think its the internet. Also tried deleting the app and wiping everything to start agin. I absolutely adore music and my music and would do ANYTHING to sort this problem.
