I seem to be running into a small problem while trying to sync some local files on my desktop to my Andriod device. In a specific scenario, I own the Snarky Puppy album "We Like it Here" which was recently taken off of spotify. Because of that, I added the local version I had bought to the playlist I had their music in. The music plays on my desktop, no problem. I tried to sync this playlist to my phone, and all of the other tracks, except for the select Snarky Puppy songs, will sync.
In troubleshooting I have searched the Community posts related to local file syncing, but I have not been able to use those solutions to fix my specific problem. As a precaution I have reinstalled spotify on both devices, and still nothing has changed.
As I looked further into the problem, to see if it was possibly the file format or other songs that had the problem, I recorded a number of different occurences in which I wasn't able to sync some classical music from my library from my desktop to my phone either.
