On your Spotify desktop app, click your profile picture at the top of the screen and select Settings. Under Local Files, toggle the button next to “Show Local Files.” Depending on where you want to download your music files, you can change the buttons next to “Downloads” or “My Music.” Alternatively, you can type Add Source and manually select which folder you want to pull your local music files.
If you’re having trouble uploading your local files to your Spotify app, you can contact Spotify for help. Once you’re logged into your account, you can send a message to its customer service experts or DM @SpotifyCares on X (formerly Twitter).
When adding local files to Spotify, it’s best to only upload songs that you’ve obtained legally. Alternatively, if you don’t have a way to buy the music of your favorite artists, you can try to find them on other platforms and support them by buying their merchandise or going to their shows.
