Hi, I know this has been mentioned a thousand times and I've read so many posts but nothing is working and it's so frustrating, I'm on the verge of cancelling my premium subscription. 75% of the downloaded songs won't play offline despite having the green arrow next to them, when touched the timer stays on 00.00 and nothing plays, I've reinstalled the app, I've spent hours redownloading albums and playlists, each time I eagerly await the downloaded to finish (we're talking hundreds of songs), thinking this time the problem will be fixed and yet again most of the songs just will not play. The reboot doesn't work, the app is up to date, it's driving me up the wall. Please help!
