Needs updating badly

Problems:
1. Low quality album pictures for every album. If these pictures are pixilated how can I trust the sound quality is what they claim?

2. Downloading songs is confusing and tedious. There should be a way to download your whole library and see your download queue

3. When I am trying to drag the dot that sets the play time of the song, it often skips the song or goes to the previous song instead.

4. Integration without iOS is poor. Scrolling is clunky and laggy, and the built in iOS music player that is accessible from the lock screen does not communicate with the app reliably

5. The interface and graphic design of the app do not look as sleek as competing apps, it almost looks like it was designed for children

Edit 7/30/17: the app has gotten worse. The time on the song will be counting down as if it is playing but there will be no volume. It randomly cuts in and out doing this, and songs will abruptly become muted. This happens often when the app is running in the background. There is still no "download all" button for your library and no way to add more than 1000 songs to a playlist. The app freezes and lags (mostly on scrolling and navigation)and crashes all the time. Songs that are supposed to be download randomly become unavailable for offline play. If these issues are not addressed promptly I will be switching to Spotify Tidal or Deezer. I hope I will not have to do this because reassembling a music library is tedious but not as tedious as using this app. I expected more from a Google app
