I have a 7th generation ipod touch and whenever I use the Music app when connected to the internet then that little 'processing' or 'thinking' circle appears in the upper left on the status bar. What could be the reason for this behavior? I'm not streaming music from Apple Music, I am simply playing downloaded music on the app. That little circle appears even when the app is simply open without playing music. Is it trying to download album covers that are missing or what?
