I just did a clean install of El Capitan on my iMac. I come to set up iTunes. I sign into my store account and I see the songs I've purchased. But also listed as available for download are some of the songs and albums that I've added to iTunes in the past from CDs, and which I've never purchased from Apple. Yet there they are available for download. Has anyone else experienced this? I don't use Apple Music or iTunes Match.
