Syncing Songs Not In Spotify Archives to Mobile from Local Files

[madison_lovely]

So Sleeping At Last just released a new Christmas album, but it's not avaliable on Spotify because it's working through a charity site. So I downloaded it on my Mac and synced the files with my local library in Spotify on the mac. I can play them from there but I want to listen to them on my mobile too.

So I made a playlist specifically for these new local songs on my Mac and it showed up on my phone (like normal). Only three songs downloaded when I licked the "avaliable offline" button on my iPhone 6, and I think that's because they linked to songs on various Christmas albums because those were older ones that have been used other places. But the rest of the album is still greyed out and it says "waiting to download". I don't even have the grey arrow that says it's trying to download. Anyone having the same issue? Any fixes? Can I not download local files if it doesn't have a link to the spotify archives? 

Thanks
