Mac/iPhone Local Files sync

[EDB1511]

Okay so I use Soundcloud for some tracks that aren't available on Spotify but I don't want to pay for both services. I can still use souncloud but then there are ads, so the other day I found out about local files I was really excited. I downloaded some tracks from soundcloud and I have now uploaded them to spotify on my MacBook. All good so far. Now, I want these tracks to be on my phone, not my Mac, because that's where I listen to music. 

So, as it says to do, I have put these tracks in a playlist, connected both devices to the same wifi network and pressed offline sync on my Mac, which was supposed to then make the songs playable on my phone. No such luck. The songs are greyed out and it will only let me play them when its through my mac. Any solutions?
