The Transfer to Spotify app is the easiest way to transfer local songs and music to Spotify. It allows you to do that in a quick and easy way, without having to do anything else.
In just a few minutes, you can start listening to your favorite songs on Spotify. All you have to do is install the app, select the music you want to transfer, and click "Start."
Once you're finished listening, you can simply remove the song from your device to clear up device storage. The songs you remove will be removed from your transfer list and will no longer appear on the Spotify app on your device.
