It Works… But youre better off with using a browser
This app is extremely buggy. There was an issue with the volume resetting to the default on each new song. In this update they were supposed to fix it and they did only partially. Ive had the same bug happen to me for a couple of different songs now, but not every one. For the songs where things are "fixed" the song plays for probably half a second at default volume and then is changed to the volume set in the app. On my headphones that means blaring music for half a second and then back to normal volume.
Ive had problems where the app would start playing even though the display showed it was still loading, and the controls were non-functional (play/pause, next, prev did nothing). The only thing I could do was quit the app and launch it again. Unfortunately youre probably better off just using a web browser.
