Buggy and featureless vs android app
No iPhone X UI optimization
Buggy, music will frequently stop playing and be unable to skip, does not handle moving from wifi to cellular data if cell data is disabled in the app settings (songs that are downloaded to the device will stop playing)
Numerous features are missing vs the Android Play Music app, such as reordering songs in the now playing queue and adding a song to play next
