Account being used somewhere else
Spotify is licensed for personal use, so you can only play from one device at a time.
If your music stops and you see a message explaining that Spotify has been paused because the account is being used somewhere else, check your account isn't being used elsewhere, then click play to resume.
If you’ve left your account logged in somewhere, or you're worried someone might have accessed your account without permission, you can sign out remotely from your account page. For extra safety, you can change your password.
Tip: Seamlessly stream from one device to another with Spotify Connect.
