For the last year and a half or so this app has insisted on streaming all my music, even if it is downloaded on my device, wasting my data. Then it started playing other people's random playlists instead of the music I actually paid for and downloaded. If I wanted whatever someone else was listening too I would ask someone I know. I was able to use another app to listen to what I bought, until the new "improvement" now it has to be used through this garbage app.
