My iPhone is paired with my car stereo. Every morning I must start music and I MUST pick the playlist. I don't play any other music. If I don't do this, Apple, in its infinite wisdom, decides that I want to play all the music that I have put into iCloud. That is a ridiculous assumption, since I have ripped all my CD's and put them in the Cloud with iTunes Match. I bought a lot of those CDs for just a couple songs. I still want the songs available. I just do not normally want to EVER play them.
I have a playlist with about 500 songs. This is what I want to play every day, except for rare occasions.
I want my phone to just play from the most recently played playlist, not all my music. I can't imagine anyone wanting it to not continue playing from what it last was playing. It would be so simple to implement store the playlist name once selected. Store the track index. On music stop, store the time into the track. Or periodically update this, like every 30 seconds.
I want access to all my music through the cloud and I want it to only play music that I have downloaded to the phone.
And to top it off, with iOS 10, there is not even an indicator to show that you are playing from a playlist. At least with iOS 9, the Up Next would show that the upcoming tracks were from a playlist.
Get it together Apple. This music app of yours is something developers should be embarrassed to have made.
