I found out last night that you can use your desktop instance of Spotify to share your own MP3s to your mobile device. The setup is a bit technical and not for the impatient.

Here’s the problem I ran into and how I fixed it. It worked on an old IOS 12 device right away but I wanted the files on my main phone which is running iOS 14.

On my desktop I had already:

• enabled Local Audio Files in Spotify settings

  • added in the folders that have the MP3s I wanted to import

• added those songs to a playlist

On my phone:

• enabled Local Audio Files in Spotify settings

• Chose to download the list that had the local MP3s

On my iOS 14 device I was seeing this error:

The problem was that I hadn’t enabled Local Network access for the Spotify app on my iphone. Make sure that it is enabled:

And once things are working you should see that One device is currently available for syncing:

After that, the downloads proceed without further prompting.
