STILL useless as a replacement for Google Play Music. Still can't browse library on device by album artist, only by artists of individual tracks (so doesn't work for compilations or collaborations). Selecting an artist lists all their tracks A-Z, not grouped into albums and in track order. This is basic functionality for a music player. And then it stops playing if the phone goes to sleep, so you have to keep waking it up. Please fix it or bring back the old app.
