I noticed about two weeks ago that my Spotify app was seemingly picking and choosing which songs it actually wanted to download when I marked them as Available Offline.  I cannot seem to spot any rhyme or reason as to why this is happening.

- I have an iPhone 5s with all iOS and app updates current.

- I have Spotify Premium.

- I have over ten gigs of available space for music

- I have tried to download over both my home and work wifi networks which I have never had any issue with before.

- I have hard restarted my phone.

I am trying to avoid deleting the app and reinstalling because I have a lot of music waiting for download and I don't want to go through that hassle again.  The part that has me baffled is that on some albums that I've made the entire album available offline, only parts of them are.

And while I have all of these songs waiting for download, I added Selena Gomez's album to the wait list, but it's now downloaded and none of the rest are.

I haven't the slightest clue what is going on, but it's driving me insane.  Any help would be appreciated!
