iTunes is showing me songs I have never bought in my iTunes Library (Mac). Help me stop it!

iTunes auto-download is not on. Never subscribed to iTunes Match or Apple Music (turned off in settings). I just want it to stop GIVING me free songs. It is clogging up my playlists (which downloads the song when on shuffle and the song comes up, annoying). Deleting them is a chore and you cannot delete them, only hide them (super annoying).
