Burned CD music lost on PC
I burned CDs and loaded them onto a portable storage unit connected to my Windows 10 PC. They were in an iTunes folder. The music appears on my IPhone ITunes app, however they no longer appear on my iTunes app on my Windows PC, and the ITunes folder on the portable storage unit no longer contains the burned music. Is it possible to download this music back onto my computer from my iTunes iPhone app?
