Close to useless, at least in Germany. Since December 2021 I noticed an increase in tracks that "cannot be streamed", as the app puts it. This got so worse, that even the yearly playback was close to a joke with every third track not being able to be streamed. Right now you can not use this app while doing sport or simply listening to music while showering, because the playlist just stops when a track is encountered which "cannot be streamed". And it gets worse every month it seems...
