CDs loaded to iTunes now missing from iTunes
A long time ago I copied many many CDs onto my iTunes Library. The iPod they were on is now broken and cannot be used so I am trying to access that music on an Android phone now. I have loaded Apple Music onto my Android phone and I can see some music, it seems to be music I purchased onto iTunes. I cannot see any of the CD music I saved to iTunes long ago. I then loaded the latest version of iTunes onto my PC Laptop (not Mac or Apple) but again my saved CDs are not appearing on the iTunes Library. How can I get all my music back please? I want to be able to access all my saved CDs from my Android phone, both purchased onto iTunes and saved onto iTunes from CDs.
Thank you
