Remove, reissue, repackage

Nothing lasts forever. Artists or record labels may remove their music from Apple Music, or shows and movies may be deleted by the studio before being remastered, repackaged and reissued on iTunes as a whole new release you can’t just download even though you bought it before. That’s why it’s important to ensure that you back up any media you buy; if you love it and don’t want to lose it, back it up.
