Great platform for music purchases, but the mobile app is an absolute catastrophe on my phone. I can't get the app to play a single purchased album without problems. At first, every track I purchased is assumed to be a "preview", making me wait for about 10-30 seconds until the track finally starts. Then, it keeps saying "It's impossible to play this track" at random, halting playback in the process. Awfully long time between tracks - buffering seems to be no option for this app.
