I downloaded the newest update today. Everything is going good. I leave my house, head to band practice and unbeknownst to me, my phone started re-downloading my entire music library. I didn't even have the app running in the background. I had used up 202% of my monthly allotted data before I even realized what had happened. My 6gb plan rocketed up to 12.1gb used. Granted, the app is set for cellular data. But seriously? You're just going to re-download my entire library?? Without telling me? This is the third time my library has disappeared or needed to be downloaded also. I'm guessing it's a laughable question but would contacting Apple get me anywhere? I'm going to be on the hook for a ton of overage fees and I don't think that is right. I can deal with the hassle of re-downloading my library on Wi-Fi but when a service I pay money for is costing me a lot of extra money, it just doesn't seem fair. Sorry, rant over. I'm just frustrated.
