Is the iTunes music I download stored on my PC or stored in iTunes? I installed a new operating system, downloaded iTunes, logged in to my account, and I'm in but my music is not there. I thought the music I downloaded was all stored in iTunes but now I'm afraid that's probably not the case. Any assistance is appreciated.
Itunes music download are stored in your computer and not on your iTunes account, although they are related.
You can redownload those purchased music on your new iTunes.
Go to the iTunes Store and select "Purchased" from the Quick Links side bar on the right. Go through all the tabs to download again for free
