Is anyone else having this problem? I have a list named "Sync to Phone" so I can easily organize and sychronize all music to my phone from my desktop, but a large chunk of what I add to the list isn't showing up in the "on my device" section of my phone.

It's odd because they're definitely downloaded when I play them from my playlist, but I have to pin them (and download them) again to get them to show up in my actual list of albums, musicians, and songs.

You can find an example here.

In the first, you can clearly see that the playlist is pinned, yet none of the albums in the screenshot show up in my actual "on device" album list.

One thing that seems to correlate is that a lot of the music that doesn't show up on my phone properly is music that I've added from Google Play Unlimited but haven't actually uploaded from my computer. Could that be it? I didn't see anyone else having problems with the playlist feature in the past, so I was wondering if I was the only person having this issue.

Update: Still having this problem two months later, even on my new Nexus 5. No solution yet. I'm attempting to contact Google, but my first response got me nowhere ("Try turning your phone off and then on again" plus a bunch of other stuff that I've already tried).
