playlist stops playing on iPhone
I have a smart playlist in iTunes (version 12.1.2.27) called 3-star rock. The criteria are: genre is rock, last played is not in the past 30 days, grouping does not contain Holiday, rating is greater than 2 stars, limited to 5000 songs selected by random with live updating. It plays on my Mac, but when I try to play any song from it on my iPhone 6 Plus, it plays for a few seconds and stops; and the Music application reverts to the previously selected playlist or iTunes Radio station. Other playlists, including smart playlists, work as expected on the iPhone.
Probably unrelated: annoyingly, the playlist on the phone always has the songs grouped by album, in reverse alphabetical order by artist. I include this fact because it does affect the way I use the playlist: I set it to shuffle, and I scroll around at random to select a starting point.
