Seriously it is pathetic that Groove Music cannot do background downloads, be it when using another app or when the phone's screen is turned off. I had a huge number of files to download, went away, came back...and saw literally no progress was made.
Another is lockscreen controls, kinda like what you see in the Groove Music app when you play a song in portrait mode (where the artists portrait is shown in the background).
