While you can't directly assign Spotify songs as ringtones for specific contacts on Android, you can use third-party apps to achieve a similar result. Apps like Zedge or Ringtone Maker allow you to set custom ringtones for individual contacts. Download your chosen song from Spotify, use the app to trim it into a ringtone, and then assign it to the desired contact in your phone settings. It's a workaround, but it should do the trick!
