Imported playlist not available (songs greyed out)

[asvin1264]

Hi there, I am a Premium member.

The Madvilliany Album wasn't avaiable on Spotify. So i bought it seperately and imported it onto my desktop. I then made a playlist (the songs play fine on my desktop). My phone and desktop are synced with eachother so the playlist showed up in my phone library. Unfortunately all the songs are greyed out and are 'not available'. 

The songs are not DRM protected.

I have tried signing in and out.

I am using the same wifi and the pc and phone are both connected devices.

Playlist is set to available offline.

I have tried going offline and letting the mobile data sync up, but no luck either.

Advice?
